From: munnari!metro.oz!jimr@seismo.CSS.GOV [ If this line is missing you'll know the line eater still lives. ] Does anyone know a way of cancelling CTRL/S on a terminal line other than typing a CTRL/Q? Our students tend to hit CTRL/S unknowingly, wonder why the terminal hangs, and leave. I can tell that this has happened because by evening the process is still there and SHOW DEVICE indicates many errors on the line, and sometimes a timeout as well. I stop the process, but the only way I know of cancelling the CTRL/S is to locate the terminal in the laboratory (a time-consuming business) and give it a CTRL/Q. A worse problem occurs with the network which connects some of our terminals to the VAX: it sometimes sends a CTRL/S to the host then cannot easily be persuaded to send a CTRL/Q. I have tried SET TERM/HANGUP, and SET TERM/NOTTSYNC then /TTSYNC again, to no avail. We cannot disable TTSYNC permanently, because the knowledgeable users need it. We are running VMS V4.1 on a 780, with DZ-11s and Able VMZ32Ns.
