Using serial ports

I have just installed mint 10 (11 and 12 die trying to get to my graphics)

I am trying use the two serial ports which I have on PCI card. Windoze sees them as port 4 and port 5. I can see in \dev\ things like ttyS3 etc. I believe port 4 should be \dev\ttyS3 but I can't get a program to talk to this. It works fine in windows. Do I have to enable the ttyS3 in some way or in some way set it up before it will work?

I am trying to get LINUX to replace Windows in my Ham Station and I control my transmitters from the serial ports. Neil, G3RIR

Welcome to LinuxQuestions.

The following commands in the link provided will determine if your PCI card is being recognised and the ports properly configured. It is possible that ttyS2 and ttyS3 devices are being created but not actually connected to anything physical. Do you have any serial ports on the motherboard?

solved thanks

Thanks, that gave me the clue. I have found that the two ports which in Windows are port 4 and port 5 are ttyS1 and ttyS2. I have now made progress and I have one of my transmitters connected nicely to CQRLOGGER under LINUX so I am confident the others will follow.

On older systems the bios plays a very important part. Not all pci add on serial cards work as they should either their fault or the bios/system issue. Sometimes a bios update notes it as a change.
