Hallo, I had similiar problems using serial ports on openSUSE 12.1. Finally I got them working by manually editing /etc/init.d to change a parameter: run_setserial /dev/ttyS4 baud_base 921600 run_setserial /dev/ttyS5 baud_base 921600 baud_base was set to a different much higher value by default. I tried some other standard values and above value worked for me. On May 28 2012 13:54, Roger Oberholtzer wrote:

To: opensuse@opensuse.org Subject: [opensuse] Serial ports on openSUSE 12.1 We are trying to use serial ports on openSUSE 12.1. Nothing fancy or different from how they have been used in the past. Except nothing shows up on the open port.
Are there any changes to installed services in 12.1 compared to earlier releases that could have a basic change to simply reading from the serial port?
I can see that there is no problem with opening the port or setting the properties. The system calls proceed without complaint.
It is our own software as well as other apps that simply read from the ports that do not provide data.
Unfortunately, the systems are also new model computers. Never change a single component at a time... We looked around in the BIOS and see nothing related to the serial ports. So I can't guess how the serial ports could be messed up at that point.
We have used serial ports on Unix and Linux for a zillion years. The code is not new. Coupled with that fact and that other apps are not seeing data, I can only suspect the PC or the OS.
Suggestions welcome.
Yours sincerely,
