  You do not want this option when using the Multiface III card.  The
serial ports on the Multiface cards use the level 6 interrupt and if you
defer the interrupt, you will almost certainly lose lots of characters.
I think I even saw lots of errors when running at 1200 bps.

  One thing that could cause fifo overflows at any baud rate would be a
bad or miswired cable, or a misconfigured modem.  The modem must have
hardware flow control (CTS & RTS) enabled, and the cable must have RTS
and CTS wired correctly.
