Try 'beyondlogic.org' for info and sample code.

microsoft has provided an activex control for serial communication called MSCOMM .
you can use it in your program.

If you want to do that job in A DOS mode, you will use the DOS or BIOS interrupts for serial port handling.

Hey all
I was having the similar query as posted by Daniz40.
I used the example of inportb command as given in help of turboC and supplied data to serial port by using a microcontroller. But it displayed the default 0x0 as the data read.

Can someone identify the problem here.

Newer versions of Windows don't allow direct register writting.
