MORSE(6) BSD Games Manual MORSE(6)NAMEmorse — reformat input as morse code
SYNOPSISmorse [-o] [-p] [-P dspdevice] [-d device] [-e] [-w speed] [-W speed]
[-f frequency] [-s] [string ...]
DESCRIPTION
The command morse read the given input and reformat it in the form of
morse code. Acceptable input are command line arguments or the standard
input.
Available options:
-s The -s option produces dots and dashes rather than words.
-o Write 16bit signed, 44.1kHz native endian sound data to the file
specified by -P, or, if not specified, to standard out.
-p Send morse the real way. This only works if your system has
sound(4) support.
-P dspdevice
Select a different dsp device from the default /dev/dsp.
-w speed
Set the sending speed in words per minute. If not specified the
default speed of 20 WPM is used.
-W speed
Enable Farnsworth keying. The argument to -w will set the charac‐
ter keying speed and the argument to -W will set the spacing
between character and words.
-f frequency
Set the sidetone frequency to something other than the default 600
Hz.
-d device
Similar to -p, but use the RTS line of device (which must by a tty
device) in order to emit the morse code.
-e echo each character before it is sent, used together with either -p
or -d.
The -w, -W, and -f flags only work in conjunction with either the -p or
the -d flag.
Not all prosigns have corresponding characters. Use angle brackets to
create a ligature, like ‘<KA>’. The more common prosigns are ‘=’ for BT,
‘(’ for KN and ‘+’ for AR.
Using flag -d 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 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.
ENVIRONMENT
If your LC_CTYPE locale codeset is ‘KOI8-R’, characters with the high-
order bit set are interpreted as Cyrillic characters. If your LC_CTYPE
locale codeset is ‘ISO8859-1’ compatible, they are interpreted as belong‐
ing to the ‘ISO-8859-1’ character set.
SEE ALSOsound(4)HISTORY
Sound support for morse added by Lyndon Nerenberg (VE7TCP/VE6BBM)
⟨lyndon@orthanc.com⟩ and later converted to use sound(4) by Simon
'corecode' Schubert ⟨corecode@fs.ei.tum.de⟩.
Ability to key an external device added by Jörg Wunsch (DL8DTL).
BUGS
Only understands a few European characters (German and French), no Asian
characters, and no continental landline code.
Sends a bit slower than it should due to system overhead. Some people
would call this a feature.
