Implement the Modbus protocol (via RS232 or RS485)
for communication and make the MSP430 a bus-node?
www.modbus.org and google "modbus". There is plenty of already written sw.
Also on sourceforge.net.

Hello Georg,
Thanks for the tip. I'm also looking into using TCONNECTOR (I haven;t
started investigating yet). Are you (or anyone else for that matter)
familiar with a way to directly write data to the Information Memory ?
i.e. From my PC based application, I want to write X bytes of data
directly to the Information memory(such as a id/serial number). Is there a
straight forward way to achieve this without going through the IAR
Programmer/C-SPY/FET route (maybe through a Serial Port?).
Once again, your suggestions are greatly appreciated.
Regards
Dipak
