- About is DMSERDRV
- ─────────────────
-
- When ID Software shipped DOOM 1.2, many people looked
- forward to playing 2 player's via serial. We had heard
- about network users playing multi-player and we were
- jealous. Unfortunately, when the MODEM patch finally
- shipped, most player found it hard to configure and or use.
-
- The reason, SERSETUP was ID's programmer's first attempt at
- creating a serial driver; and it was not bad. Most of the
- problems resulted from not having the right modem INIT
- string.
-
- DMSERDRV, was created to not only attempt to solve several
- of the small bugs in the original SERSETUP code, but to
- also add upon it. DMSERDRV is capable of supporting baud
- rates from 9600 to 115.2k (included 16.8k). It fixes
- several of the slowdown bugs, and expands on the MODEM.CFG
- file. But most importantly, it is 100% compatible with the
- original SERSETUP.
-
-
- COPYRIGHT AND WARRANTEE NOTICE
- ──────────────────────────────
-
- The name DMSERDRV is (c) 1994, Simply Silly Software, but
- the actual program has been released in to the public
- domain. All we ask, is you distribute it without any
- modifications.
-
- The source code to DMSERDRV is available, but only if you
- request it from us. See the section titled "Contacting
- Simply Silly Software" for more information.
-
- There is no warrantee, either expressed or implied. We
- have done our best to test DMSERDRV, but hey, bugs do
- occur. If you have a problem, or find a bug, then please
- contact us.
-
-
- SYSTEM REQUIREMENTS
- ───────────────────
- DMSERDRV has the same requirements as SERSETUP, except it
- requires 65k of memory to run instead of 45k. It has been
- optimized for size, and compiled with for the 80386
- instruction set for power.

- INSTALLING DMSERDRV
- ───────────────────
-
- If you are going to use DMSERDRV with either ID's SETUP.EXE
- or a second party shell (such as MoDoom or Doom/Master 1.0)
- other than Doom/Master 2.0, then you will need to replace
- SERSETUP.EXE with DMSERDRV.
-
- First, copy DMSERDRV in to your DOOM 1.2 directory.
-
- Next, rename SERSETUP.EXE to SERSETUP.$$$ (ie: at the DOS
- prompt, type "REN SERSETUP.EXE SERSETUP.$$$").
-
- Finally, rename DMSERDRV.EXE to SERSETUP.EXE (ie: at the
- DOS prompt, type "REN DMSERDRV.EXE SERSETUP.EXE").
-
- If you are going to use DMSERDRV with Simply Silly
- Software's DOOM/MASTER 2.0, then simply copy DMSERDRV.EXE
- in to your Doom directory, and in DM, select Use DMSERDRV
- from the configuration menu.
-
-
- DMSERDRV Command Line Switches
- ──────────────────────────────
-
- DMSERDRV was designed to be 100% compatible with SERSETUP,
- from both the command line, and in MODEM.CFG! But there
- have been some additional command line parameters added.
- Here is a full listing of DMSERDRV's parameters, and what
- they do.
-
- -h : displays an online help screen
-
- -com<x> : Tell DMSERDRV which com port to use.
- <x> can be any value from 1-4.
- ex: -com2
-
- -baud <rate> : Selects the baud rate to communicate
- at. Can be any value between 9600
- and 115200. NOTE: It does not check
- to see if the baud rate is valid.
-
- -null : Sets DMSERDRV up for a game via a
- null-serial cable. It sets the
- baud rate automatically to 115200 and
- bypasses the dial or answer screens.
-
- -dial <number> : Dial a phone # and attempt to connect
- and play DOOM.
-
- -answer : Wait for the phone to ring, then
- attempt to connect and play DOOM.

-
- DMSERDRV Command Line Switches cont.
- ────────────────────────────────────
-
- The following switches, are used to help get DMSERDRV to
- work with strange modems or serial ports.
-
- -uart <portaddr> : Selects the UART port address to use.
- It must be entered in HEX, and be
- proceeded with a "0x", ie: 0x3F8.
-
- -irq <number> : Which irq to use.
-
- -vector <number> : What interrupt vector do you wish to
- use to communicate with DOOM. It
- also must be entered in HEX like -
- uart.
-
- -sendwait <xx> : When this command is added, DMSERDRV
- will wait for xx milliseconds between
- each character when sending a modem
- command. This fixes the problem with
- several modems.
-
- -cmdwait <xx> : If you use the cmdwait command,
- DMSERDRV will wait for xx
- milliseconds after sending the entire
- modem command.
-
- -nofifo : Forces DMSERDRV in to 8250 mode even
- if a 16550 exists.
-
- -extratics : Used to help slower modems
-
- All command line parameters, will override anything in the
- MODEM.CFG.
-
-
- MODEM.CFG
- ─────────
-
- When we updated the serial routines, we also expanded on
- the modem configuration file MODEM.CFG! But, in order to
- keep DMSERDRV 100% compatible with SERSETUP, the first 2
- lines of MODEM.CFG remain the same. So, the first line,
- is your modem INIT string, and the second line is the modem
- HANGUP string.
-
- We have added a third line. This only, hold the modem DIAL
- string. The original SERSETUP forced you to use TONE
- dialing, now you can select it.
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- After the first 3 lines, you can add other DMSERDRV
- parameters. They take the form "command=value". Here is a
- complete listing...
-
- comport=<x> : Use COMx (-com)
- baud=<rate> : Switch to <rate> bps (-baud)
- uart=<x> : Use a different UART port (-uart)
- irq=<x> : Use a different IRQ isr (-irq)
- vector=<xx> : INT to talk to DOOM (-vector)
- sendwait=<xx> : Pause sending char (-sendwait)
- cmdwait=<xx> : Pause after sending (-cmdwait)
- force8250=1 : Make 16550's act liek 8250's
-
- Notice how all of the options in the MODEM.CFG have a
- command line switch. This allows you to override your
- MODEM.CFG at run time. For a better description of what
- the option does, refer to the section "DMSERDRV Command
- Line Switches."
-
-
- Exiting DMSERDRV
- ────────────────
-
- From anywhere in DMSERDRV, if you press the <ESC> key, you
- will exit back to dos, hanging up the phone, and closing
- down the serial port.
-
-
- DMSERDRV, DOOM, and Modems
- ──────────────────────────
-
- DOOM, is a picky program when it comes to how you setup
- your modem. This is because of the way DOOM sends
- information via modem (or serial). Every time your screen
- is refreshed, a data packet is sent out. If you have any
- extra features of your modem turned on, it will slow DOOM
- down to a crawl.
-
- This is why the following 3 things MUST (I REPEAT MUST) be
- turned off. Flow Control (also called handshaking), Error-
- Correction protocol, and Compression. IF YOU DO NOT TURN
- THESE OFF, neither DMSERDRV or SERSETUP will work. Refer
- to your manual on how to turn them off.
-
- So other important things we found out while testing
- DMSERDRV. First, Doom plays poorly when hooked from a
- 486dx2-66 to a 386-dx40. Also, if you do not have a high
- speed 16550 UART chip, then you may not want to use 115200
- bps when playing via null-serial. It will lose characters
- on many machines.
