Hi
we use for demo Notebook with installed QNX 4.25. For completing demo we
need to add one more serial port. Is there some option how to do it? RS422
is requested but if it is not possible RS232 will be also good.
Thank
Put this line in the /etc/config/sysinit. AFTER the /bin/Dev &:
/bin/Dev.ser -t8 -b115200 &
Make sure is the node number (1,2,…), -b sets the desired
speed, -t8 enables RxFIFO in 16550AF chip. Driver will find and initialise
all available COM-ports. If there is no /bin/Dev & - add it.
Restarting the machine - run “ps” or “sin” to check if the driver is loaded.
You should see /dev/ser1 (if there are 2 COM-ports - /dev/ser2 and so on).

Hi
sorry there is some misunderstanding. We are able to work with existing
/dev/ser1 port. Our problem is that we need to add some PCMCIA or sometning
like this into the notebook to get one more serial port working under QNX
4.25

No problems either!
Your’s exactly case is shown in the last five lines of “use Dev.ser” help
screen. You should use “p1” or “p2” as PCMCIA slot 1 or 2 respectively.
