To configure auxiliary COM 1 port, use the
line
com1
command. To negate the previously issued command or to revert
to factory defaults, use the
no form of the command.

Usage Guidelines
The
line
com1
command available in config t command mode. The line
com1
configuration commands are available in config-com1
submode.
You can perform the configuration specified in this section only if
you are connected to the console port or the COM1 port.
We recommend you use the default initialization string. If the
required options are not provided in the user-input string, the initialization
string is not processed.
You must first set the user-input string before initializing the
string.
Examples
The following example configures a line console and sets the options
for that terminal line:
switch## config terminal
switch(config)#
switch(config)# line com1
switch(config-com1)# databits 6
switch(config-com1)# parity even
switch(config-com1)# stopbits 1
The following example disables the current modem from executing its
functions:
switch# config terminal
switch(config)# line com1
switch(config-com1)# no modem in
The following example enables (default) the COM1 port to only connect
to a modem:
switch# config terminal
switch(config)# line com1
switch(config-com1)# modem in
The following example writes the initialization string to the modem.
This is the default.
switch# config terminal
switch(config)# line com1
switch(config-com1)# modem init-string default
The following example assigns the user-specified initialization
string for a Supervisor-1 module to its corresponding profile:
switch# config terminal
switch(config)# line com1
switch(config-com1)# modem set-string user-input ATE0Q1&D2&C1S0=3\015
The following example assigns the user-specified initialization
string for a Supervisor-2 module to its corresponding profile:
switch# config terminal
switch(config)# line com1
switch(config-com1)# modem set-string user-input ATE0Q0V1&D0&C0S0=1
The following example deletes the configured initialization string:
switch# config terminal
switch(config)# line com1
switch(config-com1)# no modem set-string user-input ATE0Q1&D2&C1S0=3\015
The following example writes the user-specified initialization string
to the modem:
switch# config terminal
switch(config)# line com1
switch(config-com1)# modem init-string user-input
