You may not have any flow control in effect.  That could lead to (a lot
of) lost characters, which would, of course, be bad.

Mimicom has some settings to throttle ASCII transfers.  Try inserting
delays and see if it helps.  It's not a good way to deal with it if you
can get flow control working, but if not, it'll help.

Good luck
