waittimeout
Syntax: waittimeout integer
Function The wait timeout currently in effect for the PostScript
mode; i.e., the number of seconds the printer waits to
receive additional characters from the host computer
before it gives up and aborts the current job by
executing a timeout. At the beginning of a job, the
printer initializes waittimeout to the default wait
timeout returned by defaulttimeouts; but a PostScript
program may change it to any non-negative integer
value. (However, in interactive mode, the wait timeout
is always 0.)
