Hi, I have a Gateway 2000 486-25Mhz running UHC SysVR4 v2.0. I am attempting to connect a modem to either of the Comm ports, COM1 / COM2. I am guessing that these translate to tty00 & tty01. COM1 is a 9-pin connector COM2 is a 25-pin connector When I connect a Supra 2400 baud modem (known good) to COM1 I am using a RadioShark 25pin-9pin adapter, which is also a null modem. This is likely NOT supposed to be a null modem, but at least in this configuration the TR light on the modem comes on when I use: cu -s2400 555-7777 I set up the modem with sysadm, but as near as I can tell, that is a roundabout way to insert the following line in the /etc/uucp/Devices file: ACU tty00 - 2400 hayes \T I have also tried: ACU /dev/tty00 - 2400 hayes \T but this doesn't even light up the TR light. So I then connected the modem via 25pin ribbon cable to COM2 and tried adding the tty01 port to /etc/uucp/Devices via sysadm, but it kept trying to add /dev/tty0 ONLY and then I couldn't even remove it via sysadm, it would let me go thru all the rigamarole, but then say, "Not removed". I'd have to edit /etc/uucp/Devices to remove it. I don't believe I have yet tried the following, but I would appreciate any advice or recommendations about this problem. I'm apparently overlooking something simple. ACU tty00 - 2400 hayes \T with 9 pin connector (no null modem) COM1 ACU tty01 - 2400 hayes \T with 25 pin connector (no null modem) COM2 Any ideas?
