It sounds like you have the hardware flow control not working correctly.  
Make sure your modem has the rts and cts lines wired up, and that  yuo 
have the modem optioned for hardware flow control.

You see, when you log in at 2400, the modem at the host is still talking 
to the host at the full rate, and expects to be able to tell the host to 
"wait up" when the host starts to overrun the modem's buffer.  If you 
don't do that, you will see garbage on even moderately long listings.
