Is it possible to use 6 serial ports (RS232) with Linux ?

Hi,

I have an embedded Linux distro, but now we need to have support for 6
serial ports.
I want to add a PC/104 IO board, which has 4 extra serial ports.
(My main board has 2 ports)

Do I need to configure the kernel to detect these new ports?
(They will probably be on un-common IO addresses, and also the IRQ of those
4 extra ports will be shared)

If they're "standard" 16x50 UARTS, you can probably just use
the "setserial" program to tell the 16x50 driver the I/O
addresses and IRQ being used.

$ man setserial

Thanks for the info.
In fact, I do plan on using standard comports,
so I only need to setup the correct TTYS links, and parameters using
setserial.

Thanks again,
