How is COMM-DRV/Dos (COMMTSR.EXE) used with COMM-DRV/NT?

COMM-DRV/Dos's COMMTSR.EXE has the ability to either get its data from its built in serial communication interrupt handler or from the COMM-DRV/NT high speed serial kernel driver under Windows 2003, Windows XP, Windows 2000, or Windows NT. Because of the inefficiency of the serial port (16x50 virtualization) under Windows, integrating these two products allows DOS and DOS extended applications to operate efficiently under a DOS window under Windows.

Any application currently using COMM-DRV/Dos simply need to modify the COMMTSR.EXE configuration file to use COMM-DRV/NT instead of the built in driver.

Note: When using COM1 and COM2 with COMM-DRV/NT it is necessary to take control away from the Windows built in serial driver. Otherwise COMM-DRV/Dos (commtsr.exe) will be unable to open the port. <Click here> for the procedure to do this.
