Built in COM ports and Linux

Has ANYONE been able to get the built in COM ports to work under Linux? All I want is a login prompt. I can get the middle one (which appears to be "port 0") to work fine on booting up Linux during the GRUB phase - both input and output work.

But once I get the full image running - be it Linux Mint off a USB stick, or a "Linux From Scratch" system I built - I just can't get ANY of them to respond. They seem to be there, but they don't respond. I assign them various flow control options, just failures all the time.

I know the comm port (the one for S0 at least) works because GRUB is able to bring up a menu.

Anyone - ever - successfully get the serial ports to work in a fully running Linux?

By the way, on both an Intense PC, and on the IPC2, these things worked flawlessly under a running Linux. And, again, I know the port hardware isn't bad because the GRUB menu can be redirected to the serial port just fine.

tamir -

Thank you - I was able to perform the BIOS upgrade this evening, and I now have a working serial port.
