Serial Connectivity with BS1

Hi all,

Does anybody have any resources about interfacing a BS1 with a PC via serial port to send and receive commands?

I'm not just looking for the code for the stamp, but also how to actually connect to the serial port.

Thanks!

-Nick

    You can either use a MAX232 or -- if your serial port will tolerate TTL levels -- go direct. If you go direct you need to put a 22K resistor between the PCs TX pin and the pin used for SERIN on your BS1. See SERIN in our manual or help file for connections.
