NAME

     morse -- reformat input as morse code

SYNOPSIS

     morse [-elps] [-d device] [-w speed] [-c speed] [-f frequency] [string ...]

DESCRIPTION

     The morse command reads the given input and reformats it in the form of morse code.  Acceptable input are command line arguments or the stan-
     dard input.

     Available options:

     -l      The -l option produces output suitable for led(4) devices.

     -s      The -s option produces dots and dashes rather than words.

     -p      Send morse the real way.  This only works if your system has speaker(4) support.

     -w speed
	     Set the sending speed in words per minute.  If not specified, the default speed of 20 WPM is used.

     -c speed
	     Farnsworth support.  Set the spacing between characters in words per minute.  This is independent of the speed that the individual
	     characters are sent.  If not specified, defaults to the effective value of the -w option.

     -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, -c and -f flags only work in conjunction with either the -p or the -d flag.

     Not all prosigns have corresponding characters.  Use '#' for AS, '&' for SK, '*' for VE and '%' for BK.  The more common prosigns are '=' for
     BT, '(' for KN and '+' for AR.

     Using the -d flag, 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

     Your LC_CTYPE locale codeset determines how characters with the high-order bit set are interpreted.

     ISO8859-1
     ISO8859-15  Interpret characters with the high-order bit set as Western European characters.

     KOI8-R	 Interpret characters with the high-order bit set as Cyrillic characters.

     ISO8859-7	 Interpret characters with the high-order bit set as Greek characters.

HISTORY

     Sound support for morse added by Lyndon Nerenberg (VE6BBM) <lyndon@orthanc.ca>.

     Ability to key an external device added by Jorg Wunsch (DL8DTL).

     Farnsworth support for morse added by Stephen Cravey (N5UUU).

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.
