Hi ! Has anyone used/configured ISDN on his/her linux box. I'd like to know if any add-on card if required for ISDN in the PC. I already have an NT (Network Termination) Unit that provides connectivity to an ISDN digital line. regards, Sridhar --- Send e-mail to 'ilugc-request@xxxxxxxxxxxxxxxxxx' with 'unsubscribe' in either the subject or the body to unsubscribe from this list.
