I have done quite a few systems with this box and I can tell you there is not real reason to use the module. The command protocol is very simple. You might as well just speak right to the box yourself and manage the conversation in your own code. After all, you still have to create an API from the module<>Main program. Might aw well cut out the middle man since the module pretty much mimics the responses coming from the box anyway.

You simply have to open and maintain an IP connection on port 23 (TELNET) and treat it as a serial device. I always build in a routine to keep the connection alive and track issues. I will say in the systems I've done I have never seen the thing drop offline except in cases where it was physically disconnected. That would be my recommendation. E

Oh, one other thing to note about them: They are very slooooow... Some client education is required to keep them from banging on buttons.
