Activating the Modem PassThru Feature
Access to the router’s VT100-compatible user interface is provided through the
FrameSaver unit’s Modem PassThru feature, also known as Router Assist. A
dial-up connection to the FrameSaver unit is used to access the router when the
unit is set up for this use. See
Setting Up to Use the Modem PassThru Feature
in
Chapter 4,
Configuration Options
, to configure the unit for Modem PassThru
operation.
Once the unit is set up to use this feature, each time access to the router is
needed, the feature is activated from the Control menu.

Enable Modem PassThru to COM
When this feature is active, a logical connection between the unit’s modem and
COM ports is made, and data received over the modem port is transmitted out the
COM port to the router’s AUX or console port, and data received from the router
on the COM port is transmitted out the modem port. While Modem PassThru is
active, normal access to the FrameSaver unit through either its modem or COM
port is suspended.
When an escape sequence (minus, minus, minus, with a minimum of 50 ms
between each) is detected, the FrameSaver unit switches back to normal user
interface operation.
Canceling Modem PassThru Operation
When Modem PassThru is active, but access to the FrameSaver unit’s
menu-driven user interface is needed, Modem PassThru can be cancelled from
the Control menu.
