I'm looking for some information about the protocols used in Unix file
transfer programs (eg umodem). Having read the manuals I see that they
use the TERM II File Transfer Protocol (XMODEM is TERM II, type 3).

The idea is to get a dedicated micro (using an 8051) to transfer data
(as a simulated file) onto a Unix box -- using the existing commands
(umodem if possible) -- over a MODEM.

I have the C sources to various programs which use these protocols but
nowhere do they explain how the protocol works.

I can of course decode one of these programs and find out the method but
I am liable to miss something (probably important) so I hope that some
kind person out there can supply details of the protocol or a pointer to
where details may be found.


		Thanks for your time,
