Hi Everyone,
Great to find this forum!
I have software that runs with a config file pointing to /dev/ttyd1 for serial port 1 on an INDY box running IRIX5.3.
Serial port 1 physically may be damaged. Serial port 2 is available.
Is there a relatively simple way to swap comports between 1 and 2 making physical port 2 "ttyd1" and physical port 1 "ttyd2"?
I have looked in /etc/inittab am considering changing it there. 
Any help greatly appreciated.
