NAME

st − synchronous terminal control

SYNOPSIS

/etc/stload
/etc/stcntrl [ on │ off ]

DESCRIPTION

The stload command file is used to load the synchronous terminal prototype script, /etc/proto, into the designated KMC11-B microprocessor, and start execution of the script.  As supplied, stload uses /dev/kmc0; it may need local modification if another KMC11-B is being used. 

The stcntrl command is used to activate and deactivate the synchronous terminal driver. 

The /etc/rc file should contain the following multi-user entries:

/etc/stload
/etc/stcntrl on

while /etc/shutdown should have:

/etc/stcntrl off

FILES

/etc/stproto synchronous terminal prototype script

/dev/kmc?  KMC11-B microprocessor

/dev/vpm?  virtual protocol machine

/dev/st0 synchronous terminal control channel

/dev/st?  synchronous terminal user channels

SEE ALSO

kmc(4), st(4), trace(4), vpm(4). 

BUGS

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