We have one of these beasties, and it's performed superbly for over a
year.  Lately, odd things are happening.  For example, on the monthly
phone bill, I keep seeing repeated calls to the same number in
2-minute intervals, then a final longer charge.  The FAX protocol is a
CCITT T3C, and, according to the docco, it's supposed to retry on bad
lines.

My question is: does "retry" in the FAX sense mean "establish the
connection; verify that the line is ok; if not, hang up, and try
again".  If so, then a noisy line would certainly mean a lot of repeat
call attempts, which result in minimum-charge connections.  (In my
case, that meant about $15 last month!)

Also, we had one instance of a $26 charge ... hmmm?  You'd have to
send a HECK of a lot of pages for that.  (It was Toronto (416) to
Virginia (703) at off-peak, so the long distance would have normally
been around $10!)  Is there something in the makeup of FAXes that
could cause them to hang for a long time?

(I suppose what I'm really asking is: Has my FAX had the biscuit?)
