ICL 9520 POS display

[The Tall Man]

I have a model 9520 point of sale display made by
ICL. Other than self test I can't get this display
to work. Does anyone know how to get this display to work?

I toyed with a similar unit and remained foiled by the cabling until I finally woke up. I was using a straight thru cable rather than a null-modem cable. Maybe your problem is this simple?<p>If you are sure you have a good connection, the hex strings the unit expects to see are usually pretty simple. The work I did was in Java, what language are you using?
