	The Int 14h business seems to be heating up recently. Today a msg
asked about source code for an Int 14h hooker to be applied to a commercial
TCP/IP package. Alas, this is a much bigger problem than writing a driver.
	As seen from the terminal emulator side, the Int 14h interface is
called upon (invoke Int 14h) to get/send characters and status. The Int 14h
interface does not invoke the terminal emulator this way.
	Thus, the whole TCP/IP part needs to become a TSR and buffer incoming
characters awaiting the terminal emulator's request to do work. Well, most
Telnet packages call upon a resident kernel but are not TSRs themselves; far
from it. The problem then devolves down to converting the Telnet part to
be a TSR and that means redesigning it from the very beginning. The point of
who invokes whom is central.
