While listening to Damian Harden Pete heard:Modem Project

G'day Damian

We're really starting to drift off topic here but when you say QBASIC
do you mean the basic that comes with DOS 5 and above or do you mean
something like QB45 etc, if the former then you would be advised to
look around for a true compiler as the DOS supplied one is only an
interpreter and has source code size limitations and doesn't AFAIK
have the ability to call interrupts.

 DH> 'Upon opening COM2: at 19200 and initialising the modem at 9600
 DH> AS #1

As Dave Hatch mentioned you would be far better off using a FOSSIL
than the internal COM routines built into basic as the basic routines
are limited to 19200 port speed, only com1 & com2 are supported and
only at std IRQ settings, with a FOSSIL you have none of these
limitations as it takes care of all this for you and you just pass
info back and fwrd from your prog to FOSSIL via int 14h.

Not putting you down or anything but going by the questions you've
been asking i get the impression you've got quite a bit to learn
regarding coms i/o so i think your tending to jump in at a very deep
end.

Anyway i can see Ian putting on his moderator cap ready to fire off
some "get back on topic" netmail to us so why not come on over to the
AUST_QB echo and discuss it further there.
