Happy New Year, Panama..

I'm not going to be much help to you here..
I have no serial port knowledge to speak of..

Mine also work fine, at least with a modem or tnc..

My " cat /proc/interrupts " also shows no serial devices active.
It also shows no irq 3 or 4 , known to be used by the com1-4's
And yet, mine still work..

I know the microcom LOOKS for a true MODEM on the ports.
It would not respond to my TNC, although it did scan all the 1-4 ports.
I have used minicom to see my Ternimal Node Controller output,
which is a serial device, and it connected OK.

Do you have an external modem you could connect to a serial port,
in place of your serial link to your router?

In googling thru different sites about serial port usage in Linux,
many times the port names/numbers get screwy, but I'm guessing by now
that you've tried them all from com1 to com8 ..

Saw your posts, an didn't want to leave you hanging..

Happy New Year to you Ke4nt!

Thanks for the post...and not leaving me hanging.

I'm glad to hear about your IRQ process too. It's good to know I'm not totally screwed and you also see what I see.

It's also good to know that Microcom DOES NOT act like hyperterminal. I'll stop messing with it until I can dig up an old serial modem.

I have, indeed, tried ports 1 - 8 with minicom. It is damned odd that yours would work and mine wouldn't. When I hit "cntrl A" I never get lower right status to go "ONLINE". I have tried to set up like I would in hyperteminal (9600 - 8N1 - no flow control) but no dice on any ports.

I have tried Seyon (altho now I'm not so sure it's the correct program for serial connection either) and it seems to detect ttyS0 as an "active" port...but no actual connection is made to my test router either.

I checked the BIOS too. It has been recently flashed and is as new (1999) as it's gonna get. There is no serial setup or IRQ assignments for the serial ports. Only a serial port TEST that, of course, gives an OK result.

I will try to score an old serial modem. Maybe that would do the trick.

I have also googled my ass off...and just get more confused. I tried to dig into SETSERIAL...but I don't understand IRQ and how it needs to be programmed to even attempt it. The last thing I want to do is completely break this old laptop.

Thanks again for the help.

I know somebody can come up with the magic command lines or better program to get this licked!

I was just thinking...

I have a functional USB port and a USB to serial converter cable. Would it be feasible (easier) to try serial comms thru this cable vian USB? How can I see if the USB is recognized as a com port and which?

thanks,

panama
