How to connect to a serial /dev/ttyS2 connection...

I have a Cisco Switch that is connected to my computer via serial. I simply want to configure the switch via the serial connection from within a terminal.

I edited the /etc/inittab to include agetty for ttyS2 and ttyS3. The switch is hooked up to one of the two.

I ran

Code:

init q

to re-read the inittab

Ran a

Code:

ps -ef

and I can see the two agettys

I also have run a dmesg to confirm that my computer has detected ttyS terminals.

The requirements for the cisco switch connection are the following:
8 data bits
no parity
1 stop bit
no flow control
115200 bits per sec baud rate

How do I connect to /dev/ttyS2 or /dev/ttyS3?

I've tried

Code:

agetty -8 115200 ttyS2 vt100

but it just hangs.

Tried that with ttyS3 as well.

Shouldn't have to do ANYTHING with agetty...in fact, that's probably keeping you from doing what you want. Install (or run) minicom, which is like Procomm (from back-in-the-day), or Hyperterm in Windows. Set it to use /dev/ttyS2, then you're in....minicom is a serial terminal emulator.

Thank you very much.
