The interface on the PCISCC4 is direct to the chip, and so is most likely
3v3 CMOS ... interfacing to the 'DSY modem directly would not be ideal.
I have designed and laid out a RS422 interface board intended to connect the
PCISCC4 to the 'DSY modem, but as I haven't got a PCISCC4 yet it hasn't been
built or tested. I assume from the emails on the list that the card is
finally shipping (so I should find the time to order a pair !)
If anyone wants to try my design, let me know and I'll send you the
files.
