I'm thinking of writing a TSR that interecpts the BIOS serial control
interrupts and does some massaging to the data. Does anybody know if
the bluk of programs for MSDOS go through the BIOS or through a device
driver or whether they tend to hit hardware directly.

For those that hit the serial hardware directly is there any wya to
trap the hardware access?

	Thanks in advance,

	Gil
