It has been a while since I used VB6 but all that you should need to do is:

Sorry I can not add more. It has been a few years since I used version 6.

The module will sent an “OK” response over the serial port. You should read up on the MSComm object. Here is an MSDN article on it: http://msdn.microsoft.com/en-us/library/aa259393.aspx .

If you go to the link posted by RedOx and then click the “example” link on that page, you should find code that answers your question. I realise the link didn’t work for you when you first tried it, but it does work for me so try it again.
