i'm working on a project ICA (instrumentation control automation). i have this temperature controller (TC)and want to connect it to pc using hyperterminal. the problem is, this temperature controller is outdated and has 5 pin (AT) recorder. i want to connect to pc by serial port but there is no communication between TC and PC. how can i communicate these 2 things before i start making a program for it? this TC also have a temperature probe and heater.
 
usually with a serial port you could write a basic program to open the port, read in the data, then save the data, close the port (not in that order) and then do it again. the data would be available for plotting assuming you saved it to a flat file database.

the 5 pin connector has 5volts, ground, and strobe (I think) and maybe a dead line or two.

i'd be interested in how this project is coming. you can write to me at ajajaj at rediffmail.com
thanks
