Zoom uses the Rockwell chipset, which has certain known problems that Zoom
is too stupid to understand. Try this:
ModemSendFillOrder: LSB2MSB
ModemSendFillOrder: MSB2LSB
Note: Some of the hyperlinks (e.g. for the man pages)
can only work, if the HylaFAX software
and the full documentation are installed on your system.
