I'm running RH 8 kernel 2.4.18-24.8.0 on an Intel PIII with an Intel motherboard and have some serial port/modem questions.
What I'm trying to do is connect the RH box to a Sun Ultra via the serial ports using a serial null modem cable (db9f->db25). The PC is the db9f and the ultra is the db25. The cable is plugged into the ultra's ttySA port and I believe the cable is plugged into the ttyS0 port on the PC. I am using minicom to talk to the port. This scenario has caused me problems.
Here is the output of setserial ...

From running windoze I know the modem (a Supramax 56K) is on comm3 which appears to be /dev/ttyS2. Running minicom and setting it up to use /dev/ttyS2 for the port and typing any modem commands (atI, at&f, etc) does not get any response back from the modem. Also, the modem doesn't show up with the redhat hardware browser.
When setting up minicom to use /dev/ttyS0 to talk to the Ultra box I get the same issue.
The question is (I guess) are the serial ports configured the way I think they are? Are the serial ports setup properly? What give with the modem?
