Legacy Dos Com port
(too old to reply)

Is there anyone who knows of a driver or a piece of code that can direct a
USB port to a virtual COM port?

My OLD legacy Dos program opens a comport for a MOUSE, and I'm finding it
more difficult to find old serial mouse as well as new PC's not having
comports. The USB converters are no good as I still need an old mouse. Can
one direct a USB mouse to a virtual com port?

Many Thanks

Hi,

IMO, this simply isn't practical. However, a serial mouse and a PS2 mouse
are (essentially) the same, and most PCs and notebooks still have a PS2
mouse connector... And, PS2 mice still are available.

Thanks Richard

Unfortunatly my DOS program in question opens a com port and wants input
from the mouse direct from the com port. I will keep looking....

Would a ps/2 mouse and a ps/2 to serial port (db-9) adapter be sufficient?

Only if the PS2 mouse is also serial complient as well as PS2. Some
were, IIRC.

Hi,

Most, but not all PS/2 mouse designs will work with the adapter... At least,
the ones that I have tried. The best way to find out is to test it on your
own hardware. The adapters are quite inexpensive.
