I'm trying to access my Catalyst 1900 via the serial console.

I built a DB9 to RJ-45 cable by cutting a DB9 cable and RJ-45 cable in
half and soldering the appropriate ends together as defined here:

http://www.hardwarebook.net/cable/serial/cuscoconsole9.html

It is based on:

http://www.cisco.com/univercd/cc/td/doc/product/lan/28201900/1928v8x/19icg8x/19icinst.htm

The cable I built is identical to the cable described in this Cisco
manual, except it is a single piece cable (doesn't have crossover RJ-45
and RJ-45 crossover to DB9 adapter and separate modules).

I can't seem to establish a serial connection between my Linux PC serial
port and the Catalyst 1900.  I'm using minicom.  I've tried using
/dev/ttyS0, /dev/ttyS1, /dev/ttyS2, and /dev/ttyS3 to no avail.  I'm not
even sure the serial ports on this machine work, since I've never tried
to use them before.  (I have an internal modem at /dev/ttyS4 that worked
a few years ago, but is now broken.)  I've set the port to 9600, 8 bits,
no parity, 1 stop bit, and no flow control just as specified by the 1900
manual.

I assume the 1900 should send something to the serial console when it
powers up.  It probably should also send something when it receives
something from the serial console as well.

Does anyone have any suggestions concerning establishing a serial
connection with the Cisco Catalyst 1900's serial console?

Sincerely,

Ken Fuchs <kfuchs at winternet.com>
