X-Modem, Z-Modem etc. are packet systems, they send data in packets of a
certain size, X-Modem uses 256 byte packets, and Z-Modem uses 1K
packets, although I seem to recall it can use different sizes?. X-Modem
is quite simple to implement, but Z-Modem is somewhat more difficult,
but in either case I don't think it's what you really need to do.

It would be much easier to write a comms program on the PC to just save
the incoming serial data straight to disk, there's no need to get
involved in complicated packet systems.
