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

Cwdaemon was written by Joop Stakenborg <pg4i at amsat.org>, Rein Couperus <pa0r at amsat.org>, Wolf-Ruediger Juergens, DL2WRJ <WJuergens at t-online.de> and Ladislav Vaiz, OK1ZIA <ok1zia at nagano.cz>. Cwlib is taken and adapted from the unixcw package, version 2.2 by Simon Baldwin, G0FRD. FreeBSD support mostly done by Diane Bruce, VA3DB. OpenBSD support by Jason L. Wright, AI4JW.
Code maintainer for cwdaemon is Joop, pg4i at amsat.org.
