-
- This program has only been tested on a limited basis. By using it you accept
- full responsibility for any damages it causes. The program uses standard DOS
- and C calls and should function as described below, but this is not
- guaranteed. The author cannot be held responsible for any problems that arise
- due to its use. There is such a wide range of computer systems and so many
- configurations it is hard to tell where this program will end up or how it
- will be used. It worked as described below during our testing and did not
- cause any problems.
-
- ==============================================================================
-
- If you find this program useful please distribute everywhere you can think of
- free of charge. You cannot charge for the program itself but you can charge
- for the cost of the media it is distributed on and/or the labor involved.
- All files listed under MODOOM FILES must be included when distributing.

-
- MoDoom is designed to run the Doom game over a modem by connecting two modems
- together and then running the SERSETUP.EXE program passing any parameters
- present on the MoDoom command line or in the MODOOM.CFG file. If the config
- file is not present, MoDoom uses hard coded defaults that can be viewed by
- typing MoDoom /? on the command line. Any parameters passed to MoDoom on
- the command line will override any of the same parameters in the config file.
-
- MoDoom was created because the setup program with Doom would not work most of
- the time and you had to type in the settings every time you used it.
-
-
- ==================== MODOOM FILES ====================
-
- MODOOM.DOC - This file, MoDoom documentation
- MODOOM.EXE - The MoDoom executable program
- MODOOM.CFG - The MoDoom configuration file
- FILE_ID.DIZ - MoDoom description file
-
-
- ==================== INSTALLATION ====================
-
- - Copy MODOOM.EXE and MODOOM.CFG into the directory containing Doom.
-
- - Open MODOOM.CFG with any text editor and verify the commands will work with
- your modem. The settings for the config file are described under
- MODOOM.CFG SETTINGS. They work excellent with my USRobotics 14.4 Sportster
- external FAX/Modem and with my friends USRobotics 9600 Sportster internal.
-
-
- ==================== MODOOM.CFG SETTINGS ====================
-
- - The config file keywords (i.e., ModemComPort) are case-sensitive and must
- appear exactly as shown below.
-
- - The file can contain blank lines and comments as long as the comments do not
- contain keywords.
-
- - The following are the defaults for the config file:
- Dial=0
- LoadGame=-1
- Episode=0
- Mode=1
- NoMonsters=0
- Respawn=0
- Skill=4
- Number1=
- ModemDialString=AT&F&N6&K0&M0E1V1X4S11=55S0=0
- ModemAnswerString=AT&F&N6&K0&M0E1V1X4S11=55S0=2
- ModemResetString=ATZ
- ModemDialPrefix=ATDT
- ModemComPort=2
- ModemBaudRate=9600
- ModemParity=0
- ModemDataBits=8
- ModemStopBits=1
-
- - ModemDialString
- The string sent to the modem when you will be the one to call another
- Doom player. This does not need a carriage return character (i.e., ^M or
- ! or |) or pause character (i.e., ~ or a comma), but can contain the pause
- character "~" or the carriage return character "|" if needed.
-
- - ModemAnswerString
- The string sent to the modem when you will be the one to answer a call
- from another Doom player. This does not need a carriage return character
- (i.e., ^M or ! or |) or pause character (i.e., ~ or a comma), but can
- contain the pause character "~" or the carriage return character "|" if
- needed.
-
- - ModemResetString
- The string sent to the modem to reset to software defaults. This should
- take the modem out of Auto-Answer mode and put in Terminal-Ready mode.
- NOTE: If you have problems with the modem not resetting correctly after
- exitting Doom, try putting one or two ~ characters right before the
- ModemResetString (i.e., ModemResetString=~~ATZ).
-
- - ModemDialPrefix
- The prefix used before dialing the number of another Doom player. If you
- have a pulse line, you should change this to ATDP.
-
- - ModemComPort
- The serial port which your modem is on.
-
- - ModemBaudRate
- The baud rate which the port will be set to. This does not initialize the
- modem any differently, just sets the port to that rate.
-
- - ModemParity
- The parity which the serial port will be set to. 0 means no parity. 1
- means even parity.
-
- - ModemDataBits
- The data bits which the serial port will be set to.
-
- - ModemStopBits
- The stop bits which the serial port will be set to.
-
- - Dial
- If this is set to 0, MoDoom will put your modem into Auto-Answer mode by
- using the ModemAnswerString. If this is set to 1 thru 10 MoDoom will dial
- the corresponding Number#= entry in the MODOOM.CFG file. For example, if
- you have five numbers in the config file and the fifth reads
- "Number5=1234567" and you want to dial 1234567 just change "Dial=0" to read
- "Dial=5" or run MoDoom with the /DIAL5 parameter or the /DIALNUM#
- parameter to dial a specific phone number.
-
- - LoadGame
- This entry will call SERSETUP.EXE and pass it whatever game number you have
- specified. -1 means do not load a game, in other words, don't pass
- SERSETUP.EXE the -loadgame parameter. You can also load a game by running
- MoDoom with the /LG# parameter.
-
- - Episode
- This entry is to load a certain Doom Episode. 0 means use defaults and
- don't pass SERSETUP.EXE the -episode parameter. For example, to load
- Episode 3 change this line to read "Episode=3" or run MoDoom with the
- /EPIS3 parameter.
-
- - Mode
- This entry is to specify whether to start in cooperative or deathmatch
- mode. 0 means to use default mode (cooperative) and 1 means to use
- deathmatch mode. You can also run MoDoom with the /COOP or /DEATH
- parameters.
-
- - NoMonsters
- This entry is used to activate the no monsters feature. 0 means disabled,
- 1 means enabled. You can also run MoDoom with the /NOMON parameter.
-
- - Respawn
- This entry is used to activate the respawn feature. 0 means disabled, 1
- means enabled. You can also run MoDoom with the /RESP parameter.
-
- - Skill
- This entry is used to specify what skill level to start at. 0 will use
- Doom defaults (skill 1) and 1 thru 5 will use that skill level. You can
- also run MoDoom with the /SKILL# parameter.
-
- - Number#
- These entries are used to specify the numbers of other Doom players. You
- can have up to ten in the config file. These lines should be after the
- Dial= entry. Any entries above "Number10=" will be ignored but can be in
- the config file. You can also run MoDoom with the /DIAL# parameter to
- dial an entry in the config file, or you can use the /DIALNUM# to dial a
- specific phone number.
-
-
- ==================== MODEM INITIALIZATION STRING ====================
-
- - This seems to be a major problem point among Doom Modem players. The
- general idea to get your modem to work with Doom is to disable data
- compression, disable error control, and set your modem to 9600bps.
-
- - The following is a description of the commands appearing in the MODOOM.CFG
- file:
-
- AT - Modem attention command
- &F - Load the read-only (non-programmable) factory settings
- &N6 - Set the data rate to 9600bps
- &K0 - Disable data compression
- &M0 - Disable error control
- E1 - Turn echo on (usually default)
- V1 - Display verbal codes as opposed to numeric (usually default)
- X4 - Use result code set number 4
- S11=55 - Set touch-tone dialing speed to 55 milliseconds
- S0=0 - Disable Auto-Answer mode
- S0=2 - Enable Auto-Answer mode (modem answers after 2 rings)
-
- - If for some reason you want to use multiple init strings in the
- configuration file, you can do so by adding the ~ (pause) character and the
- | (CR/LF) character. For example, to change the reset string to take the
- modem out of Auto-Answer mode and reset to the factory settings you would
- change ModemResetString to read "ModemResetString=ATS0=0|~~~AT&F".
-
- - Note that MoDoom automatically puts three ~ characters at the beginning of
- the init strings and the | character at the end. The rest of the init
- string is up to you.
-
-
- ==================== RUNNING MODOOM ====================
-
- - The easiest way to play Doom over the modem is to call the other Doom
- player voice and one of you run MoDoom with the Auto-Answer parameters.
- Then when one of the modems is waiting for a call, hang up and have the
- other person run MoDoom with the dial parameters using the phone number of
- the other player.
-
- - To override any of the parameters in the MODOOM.CFG file, type MODOOM
- along with any parameters. To see a list of parameters type MODOOM /? on
- the command line.
-
- - Once MoDoom has started it will send the ModemResetString, then either the
- ModemDialString or the ModemAnswerString to your modem depending on whether
- you are the caller or the answerer. It will then display a prompt that it
- is waiting for the modems to connect. To abort the process just hit any key
- and the modem will be reset and Doom will not be run. Once the modems have
- connected, MoDoom will detect this, and run the SERSETUP.EXE program. If
- either player's screen appears and it is blank or only partially there, wait
- a minute or two. If the game doesn't begin you should restart the whole
- process and try to connect again. This has happened to us several times but
- always worked the second time. This doesn't appear to be MoDoom's fault.
-
- - When you exit from Doom, MoDoom will attempt to reset the modem by sending
- the reset string and dropping DTR.
-
-
- ==================== TROUBLE SHOOTING ====================
-
- - When Doom runs the screen is blank or only partially there.
-
- If the screen doesn't redraw after a minute or two, hit ESC and quit like
- you normally do and rerun MoDoom. Usually the second time works fine.
- This doesn't appear to be a problem with MoDoom as it happened to me
- several times before I made this program.
-
- - Upon exiting from Doom you receive the "Resetting Modem" message but no
- modem reset commands appear on the screen and the modem does not reset.
-
- Try adding one or two tildes to the ModemResetString line in MODOOM.CFG.
- For example, change "ModemResetString=ATZ" to "ModemResetString=~~ATZ".
-
- - After exiting from Doom the modem is put into Auto-Answer mode and answers
- every call.
-
- This happened during testing and was determined to be caused by the modem
- hardware defaulting to Auto-Answer mode and MoDoom was not dropping DTR so
- the modem was left in Auto-Answer mode. If adding the tilde characters as
- described above doesn't work, try changing the DIP switches on your modem
- to not default to Auto-Answer mode.
-
-
- ==================== MISCELLANEOUS ====================
-
- - A fellow Doom player and I worked for several days trying to get Doom to
- work optimally over the modem. After we created a batch file to echo
- commands to the modem and tested it thoroughly, I made this program so we
- could easily do what we did with the batch file.
-
- - Hopefully others can use this program and have as much fun as we did
- playing in deathmatch mode. But maybe you can get to bed before the next
- day comes.
