I threw this together in the matter of about 5 minutes (so it is not very
pretty - but it works). Feel free to modify it for your application.
The hex address is for the printer port lpt1 on my machine - check in
windows device manager (go to control panel-> system-> device manager) under
the properties of the lpt port to get the hex address for your printer port.
hope it helps
regards
John
