Unlikely, but possible.  (You would have to cease sending anything for at 
least 5 seconds).

Depends on the modem's intelligence.  A smart modem will send zero bits
to the line for a while (this is permitted), while a dumb modem could
fail shortly after its buffers are completely sent to the line.

It *is* possible, but I'd rather consider a bad phone line or so.  Even if
highly I/O bound, the system should be able to keep up with a 19200 bps
fax transmission (that's only 2 Kbyte/second!).
