I have written an application using C# and it is supposed to send/receive data on COM port. Of course, I'm using a laptop and have a dongle USB to serial (USB to male DB2) and now want to verify the data coming out of computer.
What is the fastest (if accurate) solution?
Your help is appreciated greatly.
p.s. base on http://zone.ni.com/devzone/cda/tut/p/id/3450#toc0
I can connect pin 2 and 3 then outputted data will loop back to computer and can read it off the serial port. Any idea?
