Setting Up to Use the Modem PassThru Feature
Dial-in access to the router is possible via the Modem PassThru feature, also
known as the Router Assist feature. The FrameSaver unit’s COM port must be
connected to the router’s auxiliary (AUX) or console port, and the COM port must
be configured for this use.
When this feature is set up and 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. 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.
