And it usually has a smaller window than uucp(-i)'s default
of 16 1K packets...

 check to see if both modems are configured for rtscts, and also
check the other ends port...  or if thats difficult reduce your
(actually what the other uucp will send you) window and/or packet-size
until no more data gets dropped.  (protocol-parameter i window,
protocol-parameter i packet-size, see uucp.info)  and give uucico a
-xabnormal flag so that it logs those individual protocol errors as it
gets them, if you still cant get it working then these might help us
making a better guess...

 well or if ppp works, you can also run uucp over tcp.
