I have an LED sign (one with scrolling text). It seems to be identical to the Sigma AS 227.

it has an RJ-11 socket and seems to be programmable through it with a serial connection.

There is a pretty decent documentation on this site 

My make-or-break question is: how do I get from a current machine with USB to an RJ-11 plug? is it (likely to be) enough to get an adapter like this one:

Then the communication seems to be rather trivial, text or hex.

Are there any others who have done this? Maybe hacked it even more? ;)

Any help and pointers are very much appreciated!

There is a pretty decent documentation on this site http://sigma.haufe.org that already gave me a lot of info.
