Knowing the manufacturer, model, and resolution is important. At the very
least, how many lines of text, and how many characters wide. Documentation
from the sign manufacturer will be extremely handy if they are anything
like the signs I've used.
My previous job was in a manufacturing plant, and we used quite a few signs
throughout the shop floor. The older signs were serial only, while the
newer ones were network attached (but were actually just the older signs
with internal ethernet->serial adapters).
Basically, you would write some subset of extended ascii to a specific IP &
port, marked up with control characters (which signify page breaks, text
size, transitions, etc). If it's a sign that won't be updated
automatically, they will probably have their own easy-to-use programming
software, though it's practically guaranteed to be windows-only.
