SYNOPSIS

cwdaemon [options] ...

DESCRIPTION

Cwdaemon is a small daemon which uses the pc parallel or serial port and a simple transistor switch to output morse code to a transmitter from a text message sent to it via udp port 6789.

OPTIONS

-d <device> Use a different device for keying.
-h Show summary of options.
-n Do not fork and print debug information to stdout.
-p <port> Use a different UDP port number (default = 6789).
-P <priority> Set cwdaemon priority, -20 to 20 (default = 0).
-s <speed> Set speed, value larger than 4 (default = 24).
-t <time> Set PTT delay, value from 0 to 50 ms (default = 0).
-v <volume> Set volume for soundcard output.
-V Output version information and exit.
-w <weight> Set weighting, value from -50 to 50 (default = 0).
-x <sdevice> Set sound device to be used.
 

DEVICES

Any serial device that supports getting and setting the modem control lines can be used. On Linux, ttyS0, ttyS1, etc. will work. On FreeBSD these devices are known as ttyd0, ttyd1, etc. On OpenBSD, these same devices are known as tty00, tty01, etc., but may vary with platform.

For parallel ports on Linux try parport0 (default) or parport1, and on FreeBSD, ppi0 (default), ppi1, etc. OpenBSD does not support parallel port operation, and defaults to ’tty00’.

For completeness, a ’null’ device is provided. This device does exactly nothing (no rig keying, no ssb keying, etc.).

SOUND DEVICES

Sdevice should be one of ’c’ (console), ’s’ (soundcard), ’b’ (both), or ’n’ (none). The default is console, which is the PC speaker.
