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.

Main Menu → Control→ 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.

Main Menu → Control→ Disable Modem PassThru to COM
