Hi Ted
Do you know who added the following patch in 2.3.19 and what its purpose is?
It's breaking systems and HOWTO's. It's getting difficult to convince serial.c to give up its lock on the ioregion if one has another driver that also drives 8250 style serial ports (such as baycom_ser_*).
Thanks Jean-Luc f5ibh@db0bm.ampr.org for finding the problem.
setserial /dev/ttySx port 0 seems to be the only way to convince serial to give up a particular port.
Tom
