How do i know what firmware is currently runnIng on the Fax Adapter?

Open a Hyperterminal connection and connect to the Fax Adapter. Once connected, the Fax Adapter will output some information. The first line will contain the Fax Adapters current firmware revision. It will look similar to the below output.

Note: You must be running V.010R or later to use the fax adapter with a Beam Device.
