COM ports in Linux, how do I set them up?

[jlh68]

Background: I have a Weather display station that is connected to my desktop via a Serial port. The software (Heavy Weather) runs on Windows, so I am using WINE. This application allows me to select from COM port 1,2,3, or 4, but my Ubuntu OS does not see any COM selections. I also have a couple of other pieces of hardware that connect via the Serial port. In fact I have three (3) physical Serial ports on the rear panel of my desktop.

Question: How do I configure Ubuntu to utilize these Serial ports. I have seen some sltuff about ttyS but none of it is descriptive enough to help me.

So I would like to have this weather station on one Serial port, my UPS communication link on another Serial port, and the third is for an infrared connection for a fun device.

Im not sure if this will help you as normally I use the comport to configure stuff or talk to modems, so I am not sure how its going to work for your particular application.

What I can tell you is that on a wiondows box you have Com 1 com2 and so on.
In Ubuntu/Linux its ttyS0, ttyS1 etc.
to find out what you have, you would rung

dmesg | grep tty

Heres the output from my machine, showing my comports available


[ 0.000000] console [tty0] enabled
[ 0.533704] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 0.533824] serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
[ 0.534306] 00:08: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[ 0.534494] 00:09: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A


tty0 is my virtual console.
ttyS0 and 1 are my comports on my machine


Normally I would use this information for configuration of my ports using minicom, but in your case, Im not sure what is required for that program to work.
