.Sh DESCRIPTION
The
.Nm
program provides control of the
.Tn Digiboard
installed with the given control
.Ar device
name.
A digiboard control
installed with the given
.Ar ctrl-device
name and provides control of individual digiboard
.Ar device Ns No s.
A digiboard
.Ar ctrl-device
is usually of the form
.Pa /dev/digi Ns Sy N Ns Pa .ctl
where
.Sy N
is the card number and starts at
.Dq 0
for the first attached card.
A digiboard
.Ar device
is usually of the form
.Pa /dev/digi Ns Ar N Ns Pa .ctl
.Pa /dev/cua Ns Oo Pa \&il Oc Ns Pa D Ns Sy N Ns . Ns Sy D
or
.Pa /dev/tty Ns Oo Pa \&il Oc Ns Pa D Ns Sy N Ns . Ns Sy D
where
.Ar N
is the card number and starts at 0 for the first attached card.
.Sy N
is the card number and
.Sy D
is the port number.
.Pp
The following flags are recognized:
.Bl -tag -xwidth ".Fl d Ar debug"
.Bl -tag
.It Fl a No disable|enable|query
Disable, enable or query the
.Em ALTPIN
settings for the given port(s).
.Pp
When ALTPIN is enabled, the CD and DSR lines are logically reversed.
This is useful when wiring serial ports to an 8 way RJ45 cable (full
10 way RJ45 cables are quite rare).
.Pp
A single ALTPIN setting applies to both of the callout and callin devices.
.It Fl d Ar debug
If the driver has been compiled with
.Dv DEBUG
