i have a microcontroller which i want to interface to my PC thorugh VB using the rs232 connection.. i wish to use the RTS/CTS as well as the DTR signal pins from the rs232..



1.RTS will be used to simply reset/start the microconotroller application(rs232 output) through a port input pinof the mcu
2.CTS will be used to simply indicate the level of a certain mcu output pin after starting the mcu application..
3.DTR will be used to toggle(RS232 toutput) another mcu input pin.

can i humbly ask for your simple coding template for this setup?thanks so much.........
