QUIET

Purpose:        Inhibits output of messages by drivers and TSRs to STDOUT
                when using commands DEVICExxx = ... and INTSALLxxx = ...
                during system start-up.

Syntax:         QUIET = <ON|OFF>
By default:     QUIET = OFF

Note:
     The command redirects all STDOUT output to the NUL device, preventing
initial loading messages made by device drivers and resident programs during
system start-up. Programs, as a rule, use the STDOUT for displaying messages
during normal operation and the STDERR in case of errors. But, there are
programs using STDOUT for error messages. Such messages won't be seen, if
QUIET= ON, this produces an impression that the system "hangs" when a
program or driver waits for data input from the console. The QUIET command,
therefore is recommended for use only after the system configuration has
been throroughly checked up.

     QUIET=YES together with LOGO=OFF, as a rule fully supresses all the
screen output.
