help me regarding RS232

Hi ,

My board is connected to RS232 conector (COM port of PC). I would like to trigger two ckts through Hyper Terminal which are outside the board. How can i do it ? Can i use any other pins of RS232 other than Rx and Tx.
This external ckt may be one CRO and one switch.

Regards

or you can use controller connected to serial port and it can do all you want
thank you
