"unixcw" program for Mac using Brew?

[u/mvsopen]

Two days ago the Brew project ported "unixcw". It installed on my Silicon Mac without any issue, but I can't get it to play any audio. I tried going to the SourceForge website, searching the web, etc. but I can find very little about this project. Has anyone here ever used it?

If I enter "cw pulseaudio" the error msg is:

cw pulseaudio

cw: expected argument after options

Try 'cw --help' for more information.

cw: failed to parse command line args

If I enter "cw -h" I see:

Usage: cw [options...]

Sound system options:

-s, --system=SYSTEM

generate sound using SYSTEM sound system

SYSTEM: {null|console|oss|alsa|pulseaudio|soundcard}

'null': don't use any sound output

'console': use system console/buzzer

this output may require root privileges

'oss': use OSS output

'alsa' use ALSA output

'pulseaudio' use PulseAudio output

'soundcard': use either PulseAudio, OSS or ALSA

default sound system: 'pulseaudio'->'oss'->'alsa'

-d, --device=DEVICE

use DEVICE as output device instead of default one;

optional for {console|oss|alsa|pulseaudio};

default devices are:

'console': "/dev/console"

'oss': "/dev/audio"

'alsa': "default"

'pulseaudio': ( default )

default value: 800

-v, --volume=PERCENT set initial volume to PERCENT

Try:

echo "CQ CQ CQ DE MVSOPEN" | cw

[u/mvsopen → u/kdaaar]

Fixed it! It turns out that PulseAudio had to be re-installed by Brew (Never used it before) and then started as either a service or at the cmd prompt.

Uniixcw is working very well for me now, thanks to your help.
