Re xcmalt:
I sometimes have found the same thing. Please realize that the
xmodem code in xcmalt is very simplified, and I haven't gotten
around to revising it.

What I find usually works a lot better is to start the send process
on the remote, then leave terminal mode and use the "$ rb", "$ rx", 
or "$ rz" as appropriate.

If the remote is a *nix, and I'm at a shell prompt on the remote, then
once again, leaving terminal mode to the XCMALT> prompt, I have good
luck with 
	$ echo sz ...options... ...filenames...
	$ echo sz ...options... ...filenames... ; rz

I find the former works on a fast trailblazer connection, while the
latter, with a forced local call to rz, seems more reliable at 2400bps.

Further, if you try the first form, and instead of seeing the ZMODEM
stuff, you get an XCMALT> prompt again, then just typing "$ rz" will do
it, thus in effect confirming that you should have used the second form.

I assume, in all this, that you do have the rzsz stuff on your machine...
