Hmmm. Let's look at the log file...

Actually, 3361 is shared by *all* 33600 capable USR modems, revision 1.
3362 would be "a 336200 capable modem, revision 2".

With X2, they changed all the IDs to 5601. Not a *very* smart thing to
do, actually...


Anyway.

Well, it's the typical "the remote end has just hung up and I can't get a
response back" problem. It usually happens if the modem has a fairly bad
end-of-page timing, there was too much line noise, the remote end failed
for some other reason, or whatever.

As fax is half-duplex, you can't know at that place whether the third page
*really* arrived at the remote site -- as you didn't get the final "yes,
fine, I got it" code, you have to assume it failed, and that's what the
modem signalling with +FHS:54.
