SERVER CLI MODEMINIT=”modem-init-string”
modem-init-string is the modem initialization string for a modem
attached to the serial CLI port.
Rights Required: SCON
This command is used to configure a modem initialization string for a modem
attached to the Serial CLI port. The modem-init-string must be enclosed in
quotes if it contains any white space characters. The default value is the ‘null
string’ (MODEMINIT=””), which indicates that there is no modem attached.
The purpose of this command is to allow attachment of an external modem to
the CPS Serial CLI port for dial-in Serial CLI access to the CPS.
It may be used as a backup connection in the event that the CPS is not
accessible from the network. It may also be used as a primary connection at
remotes sites that do not have Ethernet network capability.
This command requires that the Serial CLI be enabled, so the PORT SET CLI=
parameter must have been specified for a serial port.
When a modem-init-string is configured, this string will be sent to the cabled
modem upon the following conditions:
a) CPS initialization
b) Detection of a transition of DSR from low to high
c) Completion of a call when DCD transitions from high to low.
As a result, the modem-init-string can be changed during CPS operation and
the modem can be power cycled to cause the new modem-init-string to be
sent to the modem.
The modem must be Hayes-compatible and the modem-init-string must con-
tain at least the following command settings: MODEMINIT=”ATV1 S0=1”.
This causes the modem to issue verbose response strings and to auto-answer
the phone on the first ring.
Upon successful modem connection, type CR until the login prompt appears.
Operation is the same as if the Serial CLI were connected without a modem.
However, if carrier drop occurs, the Serial CLI session is automatically logged
off and any subsequent connection must authenticate again.
