From: Rusty Haddock <haddock%ti-csl.csnet@csnet-relay.arpa> First, flip switch #5 UP. This will set S0=1 on power up. If you get no carrier try flipping the switch that forces the Carrier Detect (CD) line high. The switch # escapes me. UNIX likes to see a carrier before it'll start talking to a tty port. There's another that forces the DTR pin high; you may as well try that one too. I've been using a Hayes SmartModem 1200 but if you're using the 300-baud only version the switches may be different. -Rusty-
