After playing around with this for awhile, I would say that I'm liable to
get rebooted at any moment during a PPP session, not just when there would
have been a furious rush of data. On one occasion I managed to get a 14000
byte
file.

Didn't help on my 476.
BTW, when I tried poking around with setserial, I got nowhere:
setserial -ga /dev/ttyS0
produced
/dev/ttyS0, Line 0, UART:undefined, Port: 0x0000, IRQ 0
Baud_base:0, close_delay:50, divisor: 0
closing_wait: 3000, closing_wait2: infinte
