Something like:

Levels are not, of course, TTL levels, rather RS-232.

Adding level-translators to your modems is trivialish.

But wait a moment..  wasn't  DRSI card  SYNCHRONOUS ?
The chip you referred to does not support it.

These days software audio modems ran in Linux userspace are able to
do that modem stuff all fine.  There may be some problem in joining
radio to audio card, of course...  Oh, and the PTT issue is there too.

Greetings,

	I would like to know if someone knows of a retailer or club/group that
has a (2 port) serial card using 16552D chip (see link
http://www.sysbas.com/e_product/e_16c552pci_view.html) in them. We have
a Debian packet which has old DRSI (ISA) cards, which needs replacing
and require something that does TTL (logic) to our 4800bd modems..
Thanks.
