VB 2005 Serial Ports

[csparks]

I am trying to write an application which among other things tests serial ports on a PCB. The PCB has a RS232 to RS422 two way conversion. Com1 and Com2 are my available RS232 ports and Com4 and Com5 are my available RS422 ports. I want to write to the RS232 port and verify that the correct data comes out the RS422 port. Then I want to write to the RS422 port and verify that the correct data comes out the RS232 port. I can’t seem to find the correct method to make that happen.

What do you have so far that isn't working for you?

I was not looking for completed code as much as serial port technique. I don’t understand the delegate method and how receiving through a delegate is accomplished.

Thanks!

I find this to be a very good discussion of delegates at their most basic.
