The files called FLXPTn.TXT (n=1..6) make up the Flex 9 source for
a limited form of Kermit. This particular Kermit was a result of work
by a former member of staff at Brighton Polytechnic. It is in use on
SWTP hardware, and has the following menu:
0 Terminal to line
1 Return to Flex
2 File send from Flex
3 File receive to Flex
4 Close server
5 Monitor on
6 Monitor off
As you can see, not quite like the other versions!
There is no numeric display to show how the transfer is progressing:
"s" is displayed for each Flex-sent packet, and "r" for received
packets. If the "monitor on" command has been used, the packets
will be displayed on the console device.
Terminal to line uses CTRL-D to return to command menu. Other
options should be self-explanatory.
One bug: the FCBs don't seem to be properly freed... once a transfer
has completed, the next transfer will always fail with "File already
in use" and that is repeated whatever the files actually used (ie it
happens when a different file is named, not just the same file name).
I split the source up into a few files, in case you have problems
with your editor. Briefly, they are ...
FLXPT1.TXT description, some definitions
FLXPT2 some of the routines for queue handling
3 more routines, and Kermit messages
4 receive section
5 send section
6 more routines, work on packets
In the source, you will find STTL assembler directives to give the
listing sub-titles. A list (to help if you want to edit source)
of where the STTL references occur is in FLXSTTL.TXT.
