I agree, ppp (or the tun/serial driver?) appeared to be disconnecting
deliberately.  I didn't see anything out of the ordinary in the log,
rather frustrating... however, we FIGURED OUT what was happening:  we had
parity even in pppconf, and the terminal server was running no parity.
Duhhhh... I suspect the serial driver was getting parity errors and giving
up on us.

Still am unsure exactly WHO was hanging up, nor why the configuration
examples were set up for even parity, but it works great with no parity--
4.5K/sec file transfers over standard Mexican phone lines. 

Thanks to all for the comments, or better put, lack thereof-- having
nobody else popping up with that trouble gave me the distinct impression
we had a configuration problem, and that was correct. :>
