There is complete documentation available for Xmodem, Xmodem-1K, Ymodem
batch, WXmodem, Zmodem, Punter, Kermit, etc. in textfile form.  I have
literature for all of these printed out and I have the files on disk
somewhere.  If you know machine language it isn't hard to write up the
simpler protocols (such as Xmodem and Xmodem-1K).  Testing them is the
hard part.  Writing your own is probably the best approach if you want
it to work the way you specified.  When I wrote the protocols for Novaterm
I used this approach so that I could standardize them all in the same
format.

The protocol doc files may be available on an FTP site, I don't know.  If
they aren't, and if there is interest, I can upload what I have.  (except
for Kermit, which is on the order of 900 Commodore blocks - I had to use
an SFD to download it and print it, and I don't have it on disk anymore!)
