- Mungfriend 3.7
- © 1995-98 Szymon Pura, David Zaroski
- FREEWARE
- BLABLA PRODUCT
-
- ============
- INTRODUCTION
- ============
-
- MungFriend is a tool for capturing raw serial output (done via
- exec/RawPutChar(), kprintf). It installs a resident (reset-proof) buffer,
- so it can survive most GURUs. Especially useful for debugging with
- Mungwall, Enforcer etc.
- Mungfriend is a replacement for Commodore's Sushi.
-
- =====
- USAGE
- =====
-
- MungFriend <command> [<command args>] [options]
-
- <commands> are: Shortcut:
-
- - INFO I
- - INSTALL S
- - CLEAR C
- - REMOVE R
- - TYPE T
- - UPDATE U
- - WRITE W
-
- <command args> are:
-
- - SIZE <n> where <n> is a decimal number (only for INSTALL)
- - [TO] <f> where <f> is a filename (only for WRITE)
-
- <options> are:
-
- - FLASH / NOFLASH
- - TRACE / NOTRACE
- - SERIAL / NOSERIAL
- - BELLS / NOBELLS
-
-
- (It seems complicated, but you'll be able to get hang of it in a second)
-
-
-
- 1. CREATING MUNGFRIEND BUFFER
-
- MungFriend install size <n> ; <n> - size of buffer (in bytes)
-
- Example:
-
- MungFriend install size 15000 ; allocate ~15 KB of a reset-proof buffer.
-
- Notes:
-
- You can't change size of buffer after installing - you must remove
- previous buffer first.
-
-
- 2. REMOVING MUNGFRIEND BUFFER
-
- MungFriend remove
-
- Removes the previously allocated buffer (see above).
-
- Notes:
-
- Since V3.7, the buffer will NOT be free'd immediately. I don't think there is
- a Kick 2.0-3.1 compatible way to do this.
-
-
- 3. CLEARING BUFFER
-
- MungFriend clear
-
- Previous buffer contents are cleared.
-
-
- 4. TYPE
-
- Mungfriend type
-
- Types contents of the current buffer on the screen.
-
- (New for V3.1): press CTRL-C to stop.
-
-
- 5. WRITE
-
- Mungfriend write [to] <f> ; <f> is a filename.
-
- Example:
-
- MungFriend write to Ram:MungFriendReport
-
- Creates a new file (called Ram:MungFriendReport) and copies current buffer
- contents to it.
-
-
-
- 6. UPDATE
-
- Mungfriend update <options>
-
- Examples:
-
- Mungfriend update FLASH TRACE NOSERIAL
- Mungfriend update SERIAL NOTRACE BELLS FLASH
-
- Just updates the options specified.
-
- Note well:
-
- You can specify options with EVERY command, not just with UPDATE.
-
-
-
- OPTIONS AVAILABLE:
-
- 1. SERIAL/NOSERIAL
-
- If NOSERIAL is on, then all raw serial output (via exec/RawPutChar())
- will be blocked. (i.e. even if there's a printer connected to the
- serial port, it won't receive any data. However, MungFriend will
- still be able to catch them in its buffer. You should normally
- turn NOSERIAL on if you don't have a printer (for speed reasons)).
- serial.device isn't affected by this option (again, only low-level
- raw output via exec debugging functions is)
-
- 2. TRACE/NOTRACE
-
- Most important option. If TRACE is on, then MungFriend will catch serial
- output into its buffer.
-
- NOTE WELL: THIS OPTION GETS DISABLED AFTER RESET !!
- After every reset or GURU 'TRACE' gets disabled. To continoue tracing,
- you have to turn it back on. Use something like: MungFriend update trace
-
- 3. FLASH/NOFLASH
-
- If FLASH is on, then every byte going through the raw serial will cause
- the screen to flash. This way you won't miss any debugging output.
- (I guess this won't work on most GFX boards)
-
- 4. BELLS/NOBELLS
-
- If NOBELLS is on, then all console bells will be filtered out.
- (Especially MungWall's and Enforcer's reports are full of those).
-
- =======
- EXAMPLE
- =======
-
- Simple DOS script:
-
- MungFriend install size 15000 trace flash nobells noserial
- Run Mungwall task all showfail nametag
- Run Enforcer deadly showpc rawio buffersize 5000
-
- When the screen flashes, new characters were catched into the buffer.
- Use the following command to check:
-
- MungFriend type
-
-
- =========
- TECHNICAL
- =========
-
- Kickstart V36+ (Release 2.0) required
-
- Assembler source included _ONLY_FOR_LEARNING_PURPOSES_
- Source is meant to be an example (at least a bad one).
- You are _NOT_ allowed to modify or assemble the source file.
