cwdaemon - main page
About
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. The program also uses the
soundcard or PC speaker (console buzzer) to generate a
sidetone.
Current version of cwdaemon is 0.11.0, it has been
released in March 2022. It is recommended to
use this version of cwdaemon with libcw 7.0.0 from
unixcw
3.6.0.
Up until version 0.9.4 this software has been developed
and maintained by Joop Stakenborg. Currently the
software is being developed by Kamil Ignacak.
cwdaemon is developed and tested mainly on GNU/Linux
system.

2014.04.23 - release of cwdaemon 0.10.1
Changes since previous release:
- Fixing bug #1 reported by Pino Zollo ZP4KFX:
cwdaemon failed to properly respond to <ESC>f
Escape request. Attempting to change sound system used
by cwdaemon caused the program to completely go silent
and to not to send replies.
- Fixing bug #2 also reported by Pino Zollo ZP4KFX:
cwdaemon has been sending replies too early, sometimes
right after starting to play Morse characters
(i.e. not waiting for end of playing the
characters). This problem has been fixed by changes in
cwdaemon source code, as well as by changes in
unixcw/libcw source code (this is why you should use
libcw version 6.1.1).
- Fixing bug #3 also reported by Pino Zollo ZP4KFX:
description of escaped request for word mode in man
page has been incorrect (wrong code of request). This
has been fixed.
- Fixing bug #4, this one discovered by me: cwdaemon
failed to correctly close network socket at exit. This
has been fixed.
Many thanks to Pino Zollo ZP4KFX for reporting bugs in
cwdaemon 0.10.0 and taking time to test fixes.
2014.01.15 - release of cwdaemon 0.10.0
Changes since previous release:
- Empty name of keying device sent with "8" network
request shouldn't cause cwdaemon to crash
anymore. Handling of empty/invalid keying device name
has been improved.
- Until now if cwdaemon was called with invalid /
unsupported / non-available sound system, it could
start with misconfigured sound system. Now cwdaemon
exits when it cannot open a sound system during start.
- When cwdaemon receives "switch to sound system X"
network request, and it fails to correctly switch to
the sound system, it falls back to "Null" audio
system. The fall back eliminates possibility of
crashing on attempt to use uninitialized sound system.
- Handling of "ptt delay" parameter has changed. Until
now when value sent in network request was negative,
the delay has been set to MAX. Now the negative value
sent with network request is ignored. When the
negative value has been passed through command line
argument, cwdaemon exits.
- Debug strings can be now printed to stdout (default,
was already available), stderr, or disc file. Check -f
/ --debugfile command line option for more
information.
- Verbosity level of debug messages can be controlled
with command line options.
- cwdaemon now accepts --long-options on systems that
support this functionality.
- Help text printed when calling cwdaemon with "-h"
command line argument has been expanded.
- Man page for cwdaemon has been expanded.
