I need to use a board with RS-485 interface into my Windows´development. Normally when I use the RS-232 interface I work with MSComm32.ocx, but this OCX control don´t work with RS-485.
Somebody know what is the problem?
Are there another OCX control for RS-485 interface?
How can I use the RS-485 interface in my development, without make a low level program?
Thanks for your help....
