ok, here's my setup.

TDM410 card with port 1 having a line to the PSTN and ports 2-4 have the telephone lines plugged in

FS version is 1.0.head (git-9dd45e3 2011-11-03 14-45-01 -0500)

freetdm.conf has full rw permissions

My problem is that I cannot configure freetdm to use this blasted card, no matter what I do.....
