I have an LED sign that connects via a RJ11 connection. I have a USB adapter that goes from USB to RJ11, however when I pull up the software there is no connection to the sign becuase it is looking for a com port. Any one know how to setup a virtual com 1 or 2 port on windows 7 x64?
Here is a pictures of the actual adapter:

You need an actual USB to RS-232 adapter and an RJ11 to DB9 adapter and a standard USB A-B cable and a standard gray phone cable (four conductor).
Paused until further notice.

Dang I was scared that may be the answer. What's the difference though between this setup and my adapter above? – James Mertz – 2010-09-14T05:56:05.593
@KronoS: The adapter you show has no electronics to convert the signal between USB and RS-232. – Paused until further notice. – 2010-09-14T07:12:59.390
Is the adapter just a plug adaptor (just a cable with connectors on each end) or a USB to serial adaptor (that has a box containing circuitry)? – Paused until further notice. – 2010-09-14T05:12:02.833
Hopefully that helps a litte. – James Mertz – 2010-09-14T05:23:34.053
