how can I "mknod" "/dev/ser1" ?

I have installed QNXNC621 into WMware,but I can’t find /dev/ser1.then ,I want to creat it with “mknod” but there isn’t that command.
well then,how can I creat it?

—I can find it after installing,but it will miss after reboot.

Thank you in advanced.

This is not Linux. QNX drivers directly maintain the pathname for each device. As a guess, if /dev/ser1 is not present then devc-ser8250 only detected one serial port and named it /dev/ser0.

Thank you,I think I can let devc-ser8250 re-detected my serial ports,don’t I?

done!Think you!
