.Sh DESCRIPTION
|
|
The command
|
|
.Nm
|
|
read the given input and reformat it in the form of morse code.
|
|
Acceptable input are command line arguments or the standard input.
|
|
.Pp
|
|
Available options:
|
|
.Bl -tag -width flag
|
|
.It Fl l
|
|
The
|
|
.Fl l
|
|
option produces output suitable for led(4) devices.
|
|
.It Fl s
|
|
The
|
|
.Fl s
|
|
option produces dots and dashes rather than words.
|
|
.It Fl p
|
|
Send morse the real way. This only works if your system has
|
|
.Xr speaker 4
|
|
support.
|
|
.It Fl w Ar speed
|
|
Set the sending speed in words per minute. If not specified the default
|
|
speed of 20 WPM is used.
|
|
.It Fl f Ar frequency
|
|
Set the sidetone frequency to something other than the default 600 Hz.
|
|
.It Fl d Ar device
|
|
Similar to
|
|
.Fl p ,
|
|
but use the RTS line of
|
|
.Ar device
|
|
(which must by a tty device)
|
|
in order to emit the morse code.
|
|
.It Fl e
|
|
echo each character before it is sent, used together with either
|
|
.Fl p
|
|
or
|
|
.Fl d .
|
|
.El
|
|
.Pp
|
|
The
|
|
.Fl w
|
|
and
|
|
.Fl f
|
|
flags only work in conjunction with either the
|
|
.Fl p
|
|
or the
|
|
.Fl d
|
|
flag.
|
|
.Pp
|
|
Not all prosigns have corresponding characters. Use
|
|
.Ql #
|
|
for
|
|
.Em AS ,
|
|
.Ql &
|
|
for
|
|
.Em SK ,
|
|
.Ql *
|
|
for
|
|
.Em VE
|
|
and
|
|
.Ql %
|
|
for
|
|
.Em BK .
|
|
The more common prosigns are
|
|
.Ql =
|
|
for
|
|
.Em BT ,
|
|
.Ql \&(
|
|
for
|
|
.Em KN
|
|
and
|
|
.Ql +
|
|
for
|
|
.Em AR .
|
|
.Pp
|
|
Using flag
|
|
.Fl d Ar device
|
|
it is possible to key an external device, like a sidetone generator with
|
|
a headset for training purposes, or even your ham radio transceiver. For
|
|
the latter, simply connect an NPN transistor to the serial port
|
|
.Ar device ,
|
|
emitter connected to ground, base connected through a resistor
|
|
(few kiloohms) to RTS, collector to the key line of your transceiver
|
|
(assuming the transceiver has a positive key supply voltage and is keyed
|
|
by grounding the key input line). A capacitor (some nanofarads) between
|
|
base and ground is advisable to keep stray RF away,
|
|
and to suppress the
|
|
minor glitch that is generated during program startup.

|
|
If your

|
.Ev LC_CTYPE
|
|
locale codeset is
|
|
.Ql KOI8-R ,
|
|
characters with the high-order bit set are interpreted as
|
|
Cyrillic characters. If your
|
|
.Ev LC_CTYPE
|
|
locale codeset is
|
|
.Ql ISO8859-1
|
|
compatible,
|
|
they are interpreted
|
|
as belonging to the
|
|
.Ql ISO-8859-1
|

|
.Sh BUGS
|
|
Only understands a few European characters
|
|
(German and French),
|
|
no Asian characters,
|
|
and no continental landline code.
|
|
.Pp
|
|
Sends a bit slower than it should due to system overhead. Some people
|
|
would call this a feature.
