Communications driver toolkit?

[Doug Precure]

Does anyone know of a good communications toolkit that can be used to build a serial communications driver with PB/DLL?

Hi Doug,

Try this.

If you're looking to write an actual Windows device driver, this can't be done with PowerBASIC. You'd probably be looking at Microsoft C or assembly language in conjunction with the MS DDK (Device Driver toolKit).

Thanks to Scott and Tom for your responses. At this point I'm not sure whether to develop the "driver" as a DLL or as an actual device driver.

Does anyone have any input as to the issues surrounding either choice?

Thanks...

A DLL is far simpler to design, build, debug, and make portable between platforms. A device driver may be required if you need to do low-level hardware access, or if you need to make the hardware available to Windows as a device. The two are rarely interchangeable. The choice should be fairly clear, depending on your requirements.

This being an external serial device, communicating via modbus, I don't think I wil need any low-level access. Thanks for the advice Tom.
