Chapter 5 SCSI Drive Installation 49
Using the /T=n Option
MINICAM.SYS uses a time out mechanism to detect certain
errors. When MINICAM.SYS issues a command to a SCSI device,
a timer is started. If the timer expires before the command com-
pletes, MINICAM.SYS assumes that something has gone wrong
with the device, and takes steps to recover. The default value for
this time-out is no time out (to accommodate slow devices such as
scanners). The time out value can be specified as an argument to
MINICAM.SYS in the CONFIG.SYS file. This argument consists
of a /T=n parameter, where n is the number of seconds you want it
to wait before timing out. For example, the line in CONFIG.SYS
that loads MINICAM.SYS would look like this:
DEVICE=C:<PATH>MINICAM.SYS /T=4
/T is the time out option, and 4 is the number of seconds you want
it to wait before timing out.
