Hi,
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?
i had a similar instance with using minicom -s option and
configuring my laptop to configure our routers. even though
you might see blank screen, if you press enter you will see
the box that you're emulating... i can't remember what the
alternative to minicom was so if you have any suggestion,
please shed some light into this :)
