12.6.23 Define Ports Dialback

DEFINE PORTS PortList
ALL
Turning on Dialback causes the SCS to check the dialback table (see Set/Define Dialback) each time a user
logs in. If the entered username is not in the table, the port is logged out. If the username is in the table, the
port is logged out and the SCS sends the dialback string to the port and awaits a second login. Typically, the
dialback string will cause the modem attached to the port to call the user back at a certain telephone number
for security reasons. Ports with dialback enabled have a 30-second time limit for entering the username
when logging in.
In order to use Dialback functionality, modem control must be enabled, and a modem profile must be
associated with the port. When Dialback is enabled, Modem Control is enabled by default. However,
disabling Dialback does not disable Modem Control; Modem Control must explicitly be disabled if so
desired.

switching terminal lines to access other sessions. Any open connections will be closed before logging out.
