LED Display Board on Serial Port

imdimd Member Posts: 4
Hi All

I'm trying to write to an LED Display Board. It has four rows, each about 7 LEDs high and can display about 40 characters each about 5 wide per row. Not too sure though.

Currently it's being controlled by some old software that's not too bad. But I want to improve on it.

I imagine the board has some driver interface so that when you write to the serial port you send an instruction to the driver telling it to set the state of the LED at a specific location.

Does anyone have any ideas/suggestions?

Please help
