How do i know what firmware is currently running on the Fax Adaptor?

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

AT08/15/2007-002 IRIDIUM-V.010R+++ATH 

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