Jordan OK'ed it, i think it's a nice one for those who need it. I once mentioned in Usenet that i've hacked morse(6) so it can control an external device like a tone generator or even a ham radio transceiver, so you could actually use that `game' for really transmitting morse code through the air. A couple of people then bugged be to send them my hack (which it was by that time). So i've now finally found some hours to clean it up (like freaking out with the transmitter no longer keyed in case someone ^c's out of the program...), and to write the man page addition. While i was at it, i also cleaned up some minor nits in Lyndon's /dev/speaker code, mainly #ifdef related stuff like handling getopt() if SPEAKER is not defined etc. enjoy & 73 Approved by: jkh, the restless...

|
|
The commands
|
|
.Nm bcd ,
|
|
.Nm ppt
|
|
and
|
|
.Nm morse
|
|
read the given input and reformat it in the form of punched cards,
|
|
paper tape or morse code respectively.
|
|
Acceptable input are command line arguments or the standard input.
|
|
.Pp
|
|
Available options for program
|
|
.Nm morse :
|
|
.Bl -tag -width flag
|
|
.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
|
|
.Pq 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

The more common prosigns are
|
|
.Ql =

|
for
|
|
.Em BT ,
|
|
.Ql (
|

for
|
|
.Em KN

|
|
.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 supress the
|
|
minor glitch that is generated during program startup.

If one of these variables (in this priority) is set to a locale ending in
|
|
.Ql KOI8-R ,
|
|
characters with the high-order bit set are being interpreted as
|
|
Cyrillic characters. In all other cases, they are being interpreted
|
|
as belonging to the
|
|
.Ql ISO_8859-1
|
|
character set.

|
|
.Sh BUGS
|
|
Does only understand a few European characters (namely German and
|
|
French), but neither Asian ones, or the continental landline code.
|
|
.Pp
|
|
Sends a bit slower than it should due to system overhead. Some people
|
|
would call this a feature.
