ICNT.MAC

The following MACRO-11 subroutines may have to be tailored
to correspond to your respective systems.

ITTOUR.MAC
TTYOUT.MAC
TWAIT.MAC

For a bit more background, this program was originally designed
to run in an RT-11 environment using DL-11W's for communication.
It was then transported over to RSX-11M 3.1 using DZ-11's and
212 modems. No loss of information was found at speeds of 300
baud when talking with ANY system, but PDP-11/70's were able
to out-talk our poor 11/34 at 1200 baud and cause us to lose
information, but usually only when XMT was checkpointed for
extended lenghts of time. Under RSX-11M v3.2 a few features
were added to the ITTOUR.MAC and INPTT1.MAC subroutines to make
use of a few v3.2 TT: driver features, such as full-duplex
and 8-bit characters. This program has been successful in
receiving and transmitting at rates up to 4800 baud on an
11/34 system (under v3.1) with no data loss. Under v3.2
there should be no loss of data at any speed.

(JLH) Made flags permenant feature to reduce CPU overhread.
(JLH) Added auto-dial of HAYES SMARTMODEM 300 (1200?)
(JLH) Added ability to insert LFs for those systems which
do not supply them.
(JLH) Restructored status reports.
(JLH) Used for data transfers across DZ at 9600 to tek 8560
and HP1000 with no data loss.
(JLH) Redesigned build file.
