[mythtv-users] Big help request for getting 2 LIRC drivers (Rx/Tx) to share COM port

Previous setup was running 2 instances of LIRC -  the i2c driver for
Hauppauge PVR card, and lirc_serial for a transmitter to control a
cable TV box.

I have now (finally and after much despair thinking it would never
work!) soldered up a combined serial port receiver/transmitter, and
wish to control both of these devices on one serial port (my system
only has one). However, after releasing the serial port via setserial,
I can modprobe one of the drivers, but as soon as I try and modprobe
the second, it (unsurprisingly) tells me the port is in use, and the
modprobe fails.

What I am after is the magic config line(s) to make them both play
together. Both instances have different major-numbers, and both load
fine on their own, and the devices are detected. Getting them both the
work on the same port is causing me nightmares! The LIRC docs say it
will work as long as different major numbers are used, but nothing
about the COM port setup.

Thanks to anyone who can help out here,

Nick
