Creating special device names

QNX SDP8.0System ArchitectureDeveloperUser

You can also use procmgr symlinks to create special device names.

For example, if your modem was on /dev/ser1, you could create a procmgr symlink /dev/modem as follows:
ln -Ps /dev/ser1 /dev/modem

Any request to open /dev/modem is replaced with /dev/ser1. This mapping would allow the modem to be changed to a different serial port without affecting any applications by simply changing the procmgr symlink.
