Hi, first off I think I can still call my self an Arduino newbie. What I want to do is have my arduino program talk to a PK-232. A PK-232 is a device called a TNC. TNC stands for Terminal Node Controller which is used for communicating with packet radio. Packet radio is a digital mode that ham radio operators use to communicate computer to computer or keyboard to keyboard. Now then, my PK-232 communcates over 9600 baud (or whatever I tell it) serial. To provide more info about the serial I will say that the PK-232 is currently connected to my serial port with a three wire connector I made(TX, RX, and GND). If you wondering what this will be used for, It's going to be an APRS weather station. APRS=Automatic Positioning and Reporting System. Go and find a weather station on the site www.aprs.fi thats what this is going to do but for now just temerature. Hopefully someone can help.
Thanks! Spencer, KJ6ART
