Hi,

Anybody worked with Unix VT220 (or 100/320) terminals. I need to design a display for a POS system and the operator console is a dumb terminal running at 9.6kbps serial. So the only way to get data from the POS terminal is to trap the serial data and parse it with the corrects field codes. For this I need to know the entire control code character for the terminal so that I can parse whatever fields I like. Any help or reference would be greatly appreciated. I have already build a prototype by analysing the data stream from the terminals and it is working. But I want to know the entire story so that future upgrades or different scenario can be handled with.

Regards

Sougata
