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.
