From Bde:
o Rewrote lots of it to be more like stty.1. The old one was too verbose and the complicated options no longer exist.

.Sh DESCRIPTION
|
||||
.Nm Comcontrol
|
||||
is used to examine and modify the bidirectional status
|
||||
of a specified
|
||||
sio communications port
|
||||
and its waiting time after DTR drop.
|
||||
By default (if
|
||||
.Ar sio_special_device
|
||||
only specified),
|
||||
.Nm comcontrol
|
||||
will print the current port state
|
||||
(if kernel was built with
|
||||
.Cm options COM_BIDIR )
|
||||
as either
|
||||
.Cm bidir
|
||||
to indicate that bidirectional operation is enabled or
|
||||
.Fl bidir
|
||||
to indicate that it is disabled, string
|
||||
.Cm dtrwait
|
||||
and current waiting time in ticks
|
||||
after DTR drop.
|
||||
To modify the status of the port or waiting time, simply
|
||||
specify the desired new state
|
||||
and/or new waiting time
|
||||
on the command line. All users with
|
||||
read access to the
|
||||
.Ar sio_special_device
|
||||
can use
|
||||
.Nm comcontrol
|
||||
to get the port's status and current waiting time.
|
||||
Only root can set a port's status and waiting time.
|
||||
By default, each port is initially unidirectional, waiting time is
|
||||
2 seconds.
|
||||
is used to examine and modify some of the special characterstics
|
||||
of the specified sio device.
|
||||
If no arguments other than the device are specified,
|
||||
it prints the settings of all controllable characteristics.
|
||||
This usage requires only read access on the device.
|
||||
Only the superuser can change the settings.

Set the time to wait after dropping DTR

to the given number.
|
||||

|

The default is 300 hundredths, i.e., 3 seconds.

It is strongly recommended that you do *not*
|

change the bidirectional status of a port while there are programs
|
||||
using the port. Read that as: if you do, and it breaks, don't yell
|

at me; that's a really weird thing to do.
