Hah! So would I. Unfortunately the end point of the PPP link is an Ascend NAS
at my ISP. When Isaid 'remote host' in my dumps above, I was referring to
a host on a network remote from my ISP which I was trying to reach. I suppose
it's remotely possible that something inbetween is throwing away packets in
exactly this peculiar pattern, but I can't trigger the problem accessing
through other ISPs (albeit using different hardware).
Anyway, I hacked pppdump to output in a format that pcap/tcpdump could
understand (after learning quickly about all the weird byte-saving compression
options -- eww), and the packets seem to be reaching the tty alright. If
*my* serial port/modem was overrunning, something would log a message, wouldn't
it? Can modems overrun when sending?

Hmm, no, not easily. I can see if connecting to different equipment makes
a difference -- I think there are some 3com boxes on a different line.
