Hi –
I have an application that runs under Redhat 7.2 that expects to see a
serial port at /dev/tty4 with characteristics 9600,N,1,1. Through my
own ignorance or perhaps through failure of the PCI serial card
(Dolphin 2-port PCI card) the application doesn’t appear to notice the
serial port. I know very little about linux and how to turn this back
on or test to see of the port has failed. Does anyone have a way (or
can VNC to my computer) to see what’s going on? Many thanks in
advance.

Michael,
You need to make sure that a proper driver is loaded for the serial
port.
If you type
cat /var/log/messages
after booting then you should see all your configured serial ports.
You can see the devices under /proc/bus/pci
cat /proc/bus/pci/devices
gives you a list of PCI devices. The serial board should be there.
If you type
lsmod
you get a list of all loaded kernel modules. The serial driver should be
there. If not, you should install one.
You can test the port with minicom.
Regards,
Jeroen.
