It can't be done without changing your comm parameters.

By definition, Xmodem is an 8/none protocol, it can't be implemented otherwise.
It is simply not compatible with any environment utilizing parity.

If you would use Kermit you wouldn't have the problem - transfer speeds
are virtually identical, especially if you use a 1K packet size, instead
of the default 70 byte one. There are Kermits available for virtually
every machine existant, and they are free! And in general, now written
in C.
