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 the more adventurous souls, the following files can be
	tried in place of ITTOUR.MAC, TTYOUT.MAC, and TWAIT.MAC to
	reduce the overhead of XMT.
	Note, however, that these routines are in the debugging stage
	and may not work very well on your (any) system:

TTYFLAG.MAC
ITTFLAG.MAC
WAITFLAG.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.
