A machine with a Gigabyte g33 motherboard and two serial expansion
cards has an interesting situation in which on each boot the serial
ports get different tty numbers. Why should they change on each boot,
and how can I prevent that?
The machine is currently running Ubuntu 10.04. I had run various

time you boot the machine, it re-maps everything, although most of the maps

You can, after the machine has finished booting, scan the tty for the new
serial ports and use them whatever you like, since the

Title: serial port problem
I am running the stable 2.4.20 kernel and today I came across a curious problem:
Trying to run cat /dev/ttyS0 caused the entire machine to hang no keyboard, no mouse - nothing.
After disconnecting the device connected (a moveable camera) the problem

My guess is that the kernel hangs at the irq call within the
serial device.
The device configuration is done using tcsetattr().
Any idea what can cause such a behavior?
Have you checked /proc/interrupts

It does. So do other OSes. BIOS is a valid point though.

This should be similar to what Linux can do to the console

Hi list.
I'm trying to connect Linux box to another one through RS-232 port.
The port is enabled and is working in Windows, where it's reported as
COM2, irq 3, base port 0x02f8.
In linux (RH7) I run
tpctl --rs2=COM2 --rs2=irq3 --rs2=0x02f8
setserial /dev/ttyS1 auto_irq autoconfig
Setserial
Hi list.
For some reason it doesn't want to work...
All I need is to connect through null-modem cable to another Linux
machine. Tried both 2.2.16 with pcmcia-cs-3.1.99 and 2.4.2 on RH7.0
Any attempts to connect to port in Minicom doesn't succeed.
Have I missed something?

hi,
the serial ports on thinkpads can be configured in bios in three different
ways: Enabled, Disabled and OS Controlled. In my experience, switching the
serial port from OS Controlled (the default) to Enabled solved the
problems - you might want to try that.
