For the Modem Port | Cisco Systems 2020 specs

Basic LS2020 Configuration Tasks

TCS hub<<A or B>> set <sa sb> <console modem> baudrate <rate>

where:
TCS hub<<A or B>>	Is the TCS hub prompt for the switch card (either switch card A or B, as
	appropriate)
set	Is the command that operates in conjunction with command arguments to
	set the baud rate for the speciﬁed switch and the speciﬁed port
<sa sb>	Denotes that the set command is to apply to switch card A or B, whichever
	is speciﬁed
<console modem>	Denotes that the set command is to apply to the console port or the modem
	port, whichever is speciﬁed
baudrate	Indicates that the set command is to set the baud rate for the speciﬁed port
<rate>	Deﬁnes the actual baud rate for the speciﬁed port

For the Modem Port:

The following is the order of precedence of the baud rate for the modem port on a Release 2 switch card:

12400 (default value)

29600

For the Console Port:

The following is the order of precedence of the baud rate for the console port on a Release 2 switch card:

19600 (default value)

219200

32400

41200

54800

638400

7300

Note The console port baud rate can be changed at any time, but the change will take effect only on powerup of the LS2020 chassis or a reset of the applicable switch card. Similarly, the modem port baud rate can be changed at any time, but the change will take effect only on powerup of the LS2020 chassis, on a reset of the applicable switch card, or when the modem port is reinitialized by means of the TCS hub init command.

Changing Modem Port Baud Rate if Modem Connection Cannot Be Established

If the modem port on a Release 2 switch card (SC2) is initialized with a baud rate other than that with which the modem can operate, you can change the modem port baud rate through either of two methods, whichever is appropriate for your LS2020 conﬁguration:

•Method 1, changing modem baud rate locally—This method requires access to the local console of your LS2020 switch.
