Subject: UUCP over a null modem link

I'm trying to connect two FreeBSD 2.1.0-RELEASE machines via UUCP over
a null modem cable.  (For various political reasons, SLIP/PPP isn't an
option.)  Things basically work except I can't transfer anything but very
small files.  Large files cause too many protocol errors.  For example:

uucico pcx - (1996-03-26 14:15:49.01 1062) ERROR: Too many 'i' protocol error
s
uucico pcx - (1996-03-26 14:15:49.01 1062) Protocol 'i' packets: sent 2, rese
nt 0, received 100
uucico pcx - (1996-03-26 14:15:49.01 1062) Errors: header 196, checksum 207, 
order 8, remote rejects 0
uucico pcx - (1996-03-26 14:15:49.55 1062) ERROR: Got hangup signal
uucico pcx - (1996-03-26 14:15:49.55 1062) Call complete (32 seconds 56832 by
tes 1776 bps)

I'm assuming this is some sort of flow control problem with UUCP because I
can connect with kermit and transfer an 800K file without any problems at 
baud rates up to 57600.  Both PCs are ASUS P55TP4N P133s with 16550 UARTS.
stty flags include:
	 hupcl clocal crtscts
and I have set dtrwait 0 drainwait 180 with comcontrol on each serial device.

I assume I'm not understanding something about UUCP.  I looked through the
/usr/src/gnu/libexec/uucp/doc/uucp.texi file but didn't see anything that
might help.  Can someone tell me what I'm doing wrong?

Thanks,
