Can I test a serial port application without actually having the hardware?

by on March 13, 2009

Q: I wrote an application using VB6 to be able to receive data from a serial port and write that data to a text file until I either tell it to stop or the connection is gone.

My question is, I have no hardware to test my application, I have VB6 installed on my laptop. Is there a way to test it without hardware. The hardware is in another building 20 min driving from my place and it cost $22,000 so I cannot get it to my office and I don’t want to go there each time to test it. I saw some ads talking about null modem but i did not get it.
