What isn't working?
Arjunwalmiki 4-Dec-12 2:01am    
It is working but data not receive from com port or i was not receive any error or how can i save output automatically at my desktop in the txt file.when i was press enter
1 st output Available port name.
2nd out when press enter bound rate 9600.
3rd out when press enter Available parity.parity<none>.
4th Data bite 8.
4th out when press enter Available stop bite.
5th out when press enter Available Handshake.
6th Name
7th Quit to exit

Ah this is homework... My guess would be you have the serial port set to the wrong port.

Sir this is my 1st project i am new in .net so pls explain me proper way than i will do proper change in my project
Arjunwalmiki 4-Dec-12 2:16am    
Sir i am using rs232 male port and the way bridge port is also male port so use the female to female cable for connection
