Hello, I have a problem with an Apple laserwriter connected to a terminal port of a VAX 11/750. Sometimes the terminal, or better the device, has hung itself. (Unit timed out). It is waiting for a <CTRL>Q but the laserwriter, for some reason, does not do that. Is there a way to reset the terminal driver, without having to reboot the entire system? Who has ever made such a reset program? Berend F. de Vries U00170@HASARA5.

Who has ever made such a reset program? There is an undocumented and unsupported DCL command that will probably do what you want. $ SET TERMINAL ttan:/XON Be aware that since this is "undocumented and unsupported" Digital will probably disavow the command and recommend against using it. On the other hand, I have used it with great success. Jim

Hello,
I have a problem with an Apple laserwriter connected to a
terminal port of a VAX 11/750.
Sometimes the terminal, or better the device, has hung itself.
(Unit timed out).
It is waiting for a <CTRL>Q but the laserwriter, for some reason,
does not do that.
Is there a way to reset the terminal driver, without having
to reboot the entire system? Who has ever made such a reset
program?

check the version of postscript that your laserwriter is using. ther is a bug in
postscript version 23 that causes the printer to behave as such. There exists a patch
for it, you can check with apple or adobe.
the version number can be found by quereying the printer, or by inspecting the power
up test page. the version number is on one of the little tables, version 1.0 is
postscript 23. Laserwriter pluses use version 32 (or later) and don't have the
problem, so an upgrage to the roms may also be a way to fix it.

Who has ever made such a reset >program? DEC has... :-) You might try doing a SET TERMINAL/XON to the hung up device. This tells the terminal driver to pretend it just received an XON (^Q) and to resume output. You may need the SHARE privilege to do this to the device if someone, like a print symbiont, owns it. I don't know where, or if, this is documented. /Kevin Carosso kvc@nrcvax.uucp Network Research Co. kvc@engvax.scg.hac.com
