I created a minirc file ttyS0.9600.8N1 that obviously specifies the use of /dev/ttyS0 at 9600 bits/sec., 8 bits/character, no parity, and one stop bit. The command I use is: % minicom -o ttyS0.9600.8N1 The -o option instructs minicom to do no initialization, thus minicom will not attempt to "dial" a non-existent modem. Unfortunately, use of this option also means that minicom will ignore the (UUCP-style) lock, so other programs could attempt using /dev/ttyS0 as it is unlocked. minicom assumes that use of the -o option means that another program has been used to initialize the serial line and it may have the serial line locked. There may be a better way to get minicom to work with the Catalyst 1900 serial console, but the above command seems to work quite well. >$ screen /dev/ttyS0 9600 vt100 This works great too! However, this command line is inconsistent with the man page. I shouldn't be surprised by man page bugs in open source software. Right? Thanks again to Munir for: # cu -s 9600 -l /dev/ttyS0 ------ Thanks to everyone else who responded! Your help was most appreciated!
