.TH ST 1M
.SH NAME
st \- synchronous terminal control
.SH SYNOPSIS
.B /etc/stload
.br
.B "/etc/stcntrl [ on \(bv off ]"
.SH DESCRIPTION
The
.I stload\^
command file is used to load the synchronous terminal
prototype script,
.BR /etc/proto ,
into the designated
.SM KMC\*S11-B
microprocessor, and
start execution of the script.
As supplied,
.I stload\^
uses
.BR /dev/kmc0 ;
it may need local modification if another
.SM KMC\*S11-B
is being used.
.PP
The
.I stcntrl\^
command is used to activate and deactivate the synchronous terminal driver.
.PP
The
.B /etc/rc
file should contain the following multi-user entries:
.PP
.RS
/etc/stload
.br
/etc/stcntrl \|on
.RE
.PP
while
.B /etc/shutdown
should have:
.PP
.RS
/etc/stcntrl \|off
.RE
.PP

.SH BUGS
The
.B stcntrl.c
file assumes that
.B /dev/vpm0
is the
.I vpm\^
device being used for the first (and usually only)
synchronous terminal controller.
If some other
.I vpm\^
device is being used, the
.B stcntrl.c
file must be modified and rebuilt.
