Actually there was a slight variation in the alternating ping returns in
the previous post, sequence numbers 6 and 7 were both returned.

Nothing else is shown using the IRQ 4 so the IRQ is OK unless it doesn't
show up in /proc/interrupts when the TA is in use. The fact that Winxx
uses IRQ 4 by default on com1 pretty well says the IRQ is OK though.

The ISP NAKed your request for a mru of 552 and requested the 1500 RFC
default. I'd suggest removing both the mtu and mru options. Removing the
mtu option won't hurt and might, by a large stretch of the imagination,
cure the problem.
In passing: The peer rejects CCP - the ProtRej - and also doesn't want VJ
header compression. Adding the noccp and novj options will stop useless
negotiations. Should not be related to the problem.
The log looked pretty normal except for the (long) 17 second interval
before you were authenticated. I'd guess the authentication is done
by a RAS or similar specialized authenticator.
I'm out of suggestions at this point except check to see if ifconfig shows
any PPP interface errors and to see what netstat -s says about ICMP. And,
for the record, I'm not anywhere near qualified to interpret the outputs of
those except by comparison to what they show here.
