serial port communication

[lennart]

I want to create an activeX DLL.
The DLL does not have a form to put an MScomm control on. The DLL however still have to be able to communicate trough the serial port.
Is the best way to do this by using API? If so - where do I find information about these API's?

Best regard/Lennart

I've tried this before with only partial success. In the end I used a form and just loaded it without showing and that seemed to do the trick even if a little clumsy and not ideal.

I'm hoping in .net this is somthing that has been addressed, but I'm not holding my breath.

Well, lennart you can have a ActiveX DLL that consist of a invisible Form which hold the MSCOmm control.
So that you 'll have all the MSComm event without rewriting it with all the heaadache API function.

Cheers!
