I have one machine that talks sync serial out 4 wires that are designed to

PCI based machine via some card... and write code on the PC that talks to
the card (ie. so the PC is talking to the host). I was thinking a PCI sync
serial card would do, but that wouldn't take care of the 56k leased line
signal. I'm guessing I'd need a sync modem that supports 56K dedicated line,
and then run that to a PCI sync serial card in the PC? Unless there is such
a thing as a PCI sync modem card that supports dedicated 56k connection?
Anyone have this type of hardware around for trade?
mmm. been a while since i done that :-)
I think you could use a 56k CSU/DSU and something as simple a ISA bus
card with an SCC on it. There used to be a linux driver for the 8530
that could keep up at 56k. There are other higher performance cards of
course.
The CSU/DSU might have a giant v.35 connector or if you are lucky just a
DB-25. I think some even had both (it's all dim now).
You'll laugh, but I ran a 56k internet connection for a few years out of
my house using a sparc station 1 running sun os. I ran the sparc serial
port (8530 based) directly into a CSU/DSU. It worked fine. I think I
hacked a sync driver I got from someone else (Phil Budne? does that sound
right Phil?)
the phone man thought I was nuts, however. I had a 56k and isdn and a
few too many pots lines. shortly after that I moved it all to
commercial space and became an isp :-)
