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?
