Hi,
If you do "sh line" you will see which tty line represent the aux port
ie..
5400-3#s lin
Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int
* 0 CTY - - - - - 0 1 0/0 -
1 AUX 9600/9600 - - - - - 0 0 0/0 -
2 VTY - - - - - 37 0 0/0 -
3 VTY - - - - - 0 0 0/0 -
4 VTY - - - - - 0 0 0/0 -
5 VTY - - - - - 0 0 0/0 -
6 VTY - - - - - 0 0 0/0 -
7/00 Digital modem - inout - - - 0 0 0/0 -
Thus, if you want to configure an async interface to use the aux port,
the async interface would be 1.
Thanks,
