If you are not choosing Xmodem because you need it for some
special reason, then it would be a fairly poor choice -- bad
performance, bad error detection, bad error recovery, etc. Why
not use the 8051 version of Kermit which is already available:
ftp://kermit.columbia.edu/kermit/c/i51*.*
And of course there is also an excellent Kermit implementation for
Windows 95:
