How to detect modem on Suh
 

The machine is SunFire V60

the OS is Red Hat Enterprise Linux WS release 4

I am trying to connect to the modem on the serial port, and it is not even recognized via minicom. Any idea? I think the device file might be the problem.

Well, if it's an external modem, hanging off the serial port, an lspci or lsusb won't show it, since it's NOT a PCI or USB device.

You say it's not recognized by minicom...what device did you try? If it's off a serial port, you have to change minicom to use the right one. Probably be something like /dev/ttyS0, S1, etc.

And have you contacted RedHat for support, since you're paying for it with your RHEL subscription?
