Sounds very much like your handshaking is not working - are you using
straight "hardware" handshaking or the auto-reliable mode on the
modem?  I run a fairly similar setup - 486DX/25, M11F V.Fast modem,
16550 with hardly any silo overflows.  BTW what DTE speed are you
using?  I have mine set to 57600 due to limitations at the other end
of the link.


BTW Rens, I tried mailing this reply direct to you but the mail
bounced - is your reply address correct?
