serial ports

I posted this originally under laptops but was suggested to repost here.

Allright I'm having troubles getting the serial port (built in on motherboard) to function on my laptop using damn small linux.

Dmesg and stty show everything set correctly there.(irq4 port 3f8 and linux and bios both agree)
I tried setserial but it says command doesn't exist?
Is this command non existent on Damnsmalllinux.
It's not existent on my version (2.0)
desktop shows ver Linux 2.4.31 on i686
or is it just my incomptence?

I've tried microcom and the autoconfigure says /dev/ttyS0 not responding.
I've turned off the IRDa port in Bios, and made sure the serial port is enabled.
cat /proc/ioports shows correct port 3F8
cat /proc/interrupts shows no entry for IRQ3 or IRQ4 (is this correct?)

I am VERY new to Linux, but have experience on windows.

serial port works fine on windows.

I thought DSL would be a very convenient way to use the laptop as a tool for monitoring serial data at work.
DSL looks excellent but my only requirement is the one function I can't get operational under Linux.

I have also tried this on my desktop and I have the same problem on that machine too.

It was not suggested to repost here. you should never post a thread twice at if it's in the wrong place, a moderator will move it. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
