Actually, it's just what the modem would send to sendfax in a normal class
2.0 conversation.  Everything after the CONNECT[0d][0a] is G3 data, up to
a <DLE><ETX> sequence.  (Normal <DLE> characters are doubled).  See the
reception code in sendfax how to handle <DLE>.

After DLE ETX, the next few status responses are sent, and then a new
page starts.

If you can keep your patience for maybe two more weeks, I shall have my
MLO tool ready, which will properly decode this :-)
