cwdaemon - morse daemon for the serial or parallel port 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 Free- BSD these devices are known as ttyd0, ttyd1, etc. On OpenBSD, these same devices are known as tty00, tty01, etc., but may vary with plat- form. For parallel ports on Linux try parport0 (default) or parport1, and on FreeBSD, ppi0 (default), ppi1, etc. OpenBSD does not support paral- lel 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. SEE ALSO

ports, port_names - Device (tty and lp) names for serial and parallel ports SYNOPSIS
Default Serial Ports: /dev/tty00 /dev/tty01 (not present on a single-port system) Parallel Port: /dev/lp0 DESCRIPTION
AlphaStation and AlphaServer systems provide one or two 9-pin serial communication ports. These ports are usually labelled 1 (COMM1) and 2 (COMM2), but they may be identified by different icons. Using the appropriate serial cable and terminator, you can connect a serial printer, external modem, or character-cell terminal to a serial port. Most AlphaStation and AlphaServer systems also provide one parallel port, for use with a parallel printer. When you add a device to your system, the installation documentation may instruct you to map the device pathname to the port. These devices are located in the /dev directory. For serial-line ports, the two default device pathnames are: This pathname always maps to 1, COMM1, the lowest port number, an icon for a terminal console, or the only serial port (on a single-port system). This pathname always maps to 2, COMM2, the next numbered port, or (if one serial port is labeled with an icon for a terminal console) the remaining serial port. If your system hardware has been extended to include additional serial ports, the pathnames /dev/tty02, /dev/tty03, and so forth, may also be available to you. However, most systems have only /dev/tty00 and /dev/tty01 as the device pathnames for serial ports. The one parallel port on an AlphaStation or AlphaServer may be labeled with the word printer or a printer icon. On some systems, the paral- lel port may not be labeled. The device pathname for the parallel port is /dev/lp0. Currently, Tru64 UNIX does not fully support parallel printers, so fewer devices are connected to this port as compared to serial ports. If you are connecting a terminal console to your system, it must be connected to the serial port mapped to /dev/tty00. For other serial devices, it does not matter which of the serial ports you choose for the connection. For example, suppose you are setting up a system that has two serial ports, labeled 1 and 2. You intend to use a serial-line terminal rather than a workstation monitor as the system console and also want to connect a serial-line printer to the system. In this case, you must connect the terminal to the port labeled 1 (with the device pathname /dev/tty00). Therefore, you must connect the printer to the remaining port labeled 2 (with the device pathname /dev/tty01). If, for the same type of system, you intend to use a workstation monitor as the system console, it does not matter which serial port you use for a serial-line printer or modem. In other words, you can connect the printer to either port 1 (with pathname /dev/tty00) or port 2 (with pathname /dev/tty01). When prompted to enter a /dev/tty** pathname by the lprsetup script or the Print configuration tool in the CDE Application Manager, you would specify /dev/tty00 if you connected the printer to port 1 or /dev/tty01 if you connected the printer to port 2. See the System Administration manual for more information on setting up consoles (including remote consoles) and printers. See the modem(7) reference page for more information on setting up modems.
