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?
Hm, is this like with the modularized lp kernel support?
Have you tried to load one of the modules available from /lib/modules/
/kernel/drivers/tty/serial/ ? Or is this yet another side effect of systemd vs sysvinit?
At first I thought it was a problem with a local driver that replaces the serial port driver for one of the ports. It handles photocells, passing along to the client the exact time the device triggered as detected in the ISR. But that was not it. Recall that I said it was a new computer? It uses a SuperMicro MB that has two serial ports. SuperMicro, however, no longer make the panels that provide access to the port that you mount on the back. So, we have purchased these elsewhere. Seems these connectors are not pin compatible with the SuperMicro MBs (even though they claim to be so). After the back panel connectors were re-wired, the data arrives. I truely could not believe that openSUSE would ship with defective serial port functionality. But I could think that some system service was getting in the way. So, openSUSE was not the culprit. It was hardware. Since I do biware (hardware and software) I did not want to take sides on this eternal question too quickly...
