    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.
