-
- This version of Kermit is derived from Kermit: A File Transfer Protocol by
- Frank da Cruz (c) 1987. Buy the book!
-
- This software is intended to be a minimalist version of Kermit. File transfer only.
- It is implemented in order move files between QNX-2 and other systems.
-
-
- Features supported:
-
- <> client
- <> get
- <> finish
- <> send
- <> remote type
- <> remote rename (if the host supports it)
- <> remote command
-
- <> server
- <> send
- <> receive
- <> finish
- <> remote type
-
- (It does not handle other commands very well)
-
- <> packets to 2048
- <> block-check 1,2,3
- <> run-length compression
- <> image and text
-
- Non-standard Features:
-
- The following features were added in order to implement a store
- and forward message passing application.
-
- -m filename
-
- This is the move command. It is the same as send with the exception
- that it deletes the file upon successful transfer.
-
- chaining a command
-
- -C host-command
-
- Can be placed on the same command line as -m. The host-command will
- be issued to the server upon successful transfer of the file.
-
- Example:
-
- /cmds/kermit -l $cti1 -i -m #1 -C "mv #2 /home/qnx2_input/#2"
-
- #1 is the QNX-2 filename
- #2 is the QNX-4 filename
-
- Testing
-
- This has been tested with MS-DOS Kermit at 9600, 19200, and 38400.
-
- This has been tested with C-Kermit-5A for QNX-4 at 9600, 19200 and 38400.

- Programming Notes by WFH; 21-July-1994
-
- I added the "Move" command -m. This deletes the file from the
- originating system when it has been successfully copied.
-
- I also modified the state machine to allow a host-command to be issued
- with a move command. For my application, I wanted to start a script
- on a host system after the file has been transferred. It is a bit of
- a hack -- but it works reliable.
-
- Originally, I thought about porting C-Kermit-5A to the QNX-2 environment.
- It could be done -- but I do not have the time.
-
- All of the code is in Kermit.c with the exception of the ccitt.crc file.
- My thought was to keep things as small as possible. I can edit the entire
- program from within QED.
-
- The primitives, tt__ and z___ are derived from stuff found in
- implementations of kermit stored on the QNX Bulletin board QUICS.
-
- I re-designed the routine rpack to extract the length of the packet
- and then do a read against the input device. This is non-portable but
- helps in accessing the disk.
-
- Notes by WFH; 28-April-1995
-
- This software has been running reliable between a QNX-2 and QNX-4 system
- for several months.
