rotctl - Online in the Cloud

PROGRAM:

NAME

rotctl - control antenna rotators

SYNOPSIS

rotctl [OPTION]... [COMMAND]...

DESCRIPTION

Control antenna rotators. rotctl accepts commands from the command line as well as in
interactive mode if none are provided on the command line.

Keep in mind that Hamlib is BETA level software. While a lot of backend libraries lack
complete rig support, the basic functions are usually well supported. The API may change
without publicized notice, while an advancement of the minor version (e.g. 1.1.x to 1.2.x)
indicates such a change.

Please report bugs and provide feedback at the e-mail address given in the REPORTING BUGS
section. Patches and code enhancements are also welcome.

OPTIONS

This program follows the usual GNU command line syntax, with long options starting with
two dashes (`-').

Here is s summary of the supported options:

-m, --model=id
Select rotator model number. See model list (use 'rotctl -l').

NB: rotctl (or third party software) will use rig model 1901 when using rpc.rotd or
rig model 2 for NET rotctl (rotctld).

-r, --rot-file=device
Use device as the file name of the port the rotator is connected. Often a serial
port, but could be a USB to serial adapter or USB port device. Typically
/dev/ttyS0, /dev/ttyS1, /dev/ttyUSB0, etc. on Linux or COM1, COM2, etc. on Win32.

Also used to specify the host and port to connect to a listening rotctld daemon on
POSIX:

-r localhost:4533

and on Win32:

-r 127.0.0.1:4533

-s, --serial-speed=baud
Set serial speed to baud rate. Uses maximum serial speed from rotator backend
capabilities as default.

-t, --send-cmd-term=char
Change the termination char for text protocol when using the send_cmd command. The
default value is <CR>. Non ASCII printable characters can be specified as an ASCII
number, in hexadecimal format, prepended with 0x. You may pass an empty string for
no termination char. The string -1 tells rotctl to switch to binary protocol. See
the send_cmd command for further explanation.

-L, --show-conf
List all config parameters for the rotor defined with -m above.

-C, --set-conf=parm=val[,parm=val]*
Set config parameter. e.g. --set_conf=stop_bits=2

Use -L option for a list.

-u, --dump-caps
Dump capabilities for the rotor defined with -m above and exit.

-l, --list
List all model numbers defined in Hamlib and exit. As of 1.2.15.1 the list is
sorted by model number.

N.B. In Linux the list can be scrolled back using Shift-PageUp/ Shift-PageDown, or
using the scrollbars of a virtual terminal in X or the cmd window in Windows. The
output can be piped to 'more' or 'less', e.g. 'rotctl -l | more'.

-v, --verbose
Set verbose mode, cumulative (see DIAGNOSTICS below).

-h, --help
Show summary of these options and exit.

-V, --version
Show version of rotctl and exit.

N.B. Some options may not be implemented by a given backend and will return an error.
This is most likely to occur with the --set-conf and --show-conf options.

Please note that the backend for the rotator to be controlled, or the rotator itself may
not support some commands. In that case, the operation will fail with a Hamlib error code.

COMMANDS

Commands can be entered either as a single char, or as a long command name. Basically,
the commands do not take a dash in front of them, as the options do. They may be typed in
when in interactive mode or provided as argument(s) in command line interface mode.

Since most of the Hamlib operations have a set and a get method, an upper case letter will
be used for set method whereas the corresponding lower case letter refers to the get
method. Each operation also has a long name; in interactive mode, prepend a backslash to
enter a long command name.

Example: Use "\get_info" to see the rotor's info.

Please note that the backend for the rotator to be controlled, or the rotator itself may
not support some commands. In that case, the operation will fail with a Hamlib error
message.

A summary of commands is included below (In the case of "set" commands the quoted string
is replaced by the value in the description. In the case of "get" commands the quoted
string is the key name of the value returned.):

Q|q, exit rotctl
Exit rotctl in interactive mode.

When rotctl is controlling the rotor directly, will close the rotor backend and
port. When rotctl is connected to rotctld (rotor model 2), the TCP/IP connection
to rotctld is closed and rotctld remains running, available for another TCP/IP
network connection.

P, set_pos 'Azimuth' 'Elevation'
Set position: Azimuth and Elevation as double precision floating point values.

p, get_pos
Get position: 'Azimuth' and 'Elevation' as double precision floating point values.

M, move 'Direction' 'Speed'
Move the rotator in a specific direction at the given rate.

Values are integers where Direction is defined as 2 = Up, 4 = Down, 8 = Left, and
16 = Right. Speed is an integer between 1 and 100. Not all backends that
implement the move command use the Speed value. At this time only the gs232a
utilizes the Speed parameter.

S, stop
Stop the rotator.

K, park
Park the antenna.

C, set_conf 'Token' 'Value'
Set a configuration parameter. It is safe to give "Token" a value of '0' (zero).
"Value" may be a string up to 20 characters.
See -L output

R, reset 'Reset'
Reset the rotator.

Integer value of '1' for Reset All.

_, get_info
Get misc information on the rotator.

At the moment returns 'Model Name'.

w, send_cmd 'Cmd'
Send raw command string to the rotator.
<CR> (or send-cmd-term, see -t option) is appended automatically at the end of the
command for text protocols. For binary protocols, enter values as \0xAA\0xBB

Locator Commands

These commands offer conversions of Degrees Minutes Seconds to other formats, Maidenhead
square locator conversions and distance and azimuth conversions.

L, lonlat2loc 'Longitude' 'Latitude' 'Loc Len [2-12]'
Returns the Maidenhead locator for the given 'Longitude' and 'Latitude'.

Both are floating point values. The precision of the returned square is controlled
by 'Loc Len' which should be an even numbered integer value between 2 and 12.

For example, "+L -170.000000 -85.000000 12\n" returns "Locator: AA55AA00AA00\n".

l, loc2lonlat 'Locator'
Returns 'Longitude' and 'Latitude' in decimal degrees at the approximate center of
the requested grid square (despite the use of double precision variables
internally, some rounding error occurs). West longitude is expressed as a negative
value. South latitude is expressed as a negative value. Locator can be from 2 to
12 characters in length.

For example, "+l AA55AA00AA00\n" returns "Longitude: -169.999983\nLatitude:
-84.999991\n".

D, dms2dec 'Degrees' 'Minutes' 'Seconds' 'S/W'
Returns 'Dec Degrees', a signed floating point value.

Degrees and Minutes are integer values and Seconds is a floating point value. S/W
is a flag with '1' indicating South latitude or West longitude and '0' North or
East (the flag is needed as computers don't recognize a signed zero even though
only the Degrees value only is typically signed in DMS notation).

d, dec2dms 'Dec Degrees'
Returns 'Degrees' 'Minutes' 'Seconds' 'S/W'.

Values are as in dms2dec above.

E, dmmm2dec 'Degrees' 'Dec Minutes' 'S/W'
Returns 'Dec Degrees', a signed floating point value.

Degrees is an integer value and Minutes is a floating point value. S/W is a flag
with '1' indicating South latitude or West longitude and '0' North or East (the
flag is needed as computers don't recognize a signed zero even though only the
Degrees value only is typically signed in DMS notation).

e, dec2dmmm 'Dec Deg'
Returns 'Degrees' 'Minutes' 'S/W'.

Values are as in dmmm2dec above.

B, qrb 'Lon 1' 'Lat 1' 'Lon 2' 'Lat 2'
Returns 'Distance' 'Azimuth' where Distance is in km and Azimuth is in degrees.

All Lon/Lat values are signed floating point numbers.

A, a_sp2a_lp 'Short Path Deg'
Returns 'Long Path Deg' or -RIG_EINVAL upon input error..

Both are floating point values within the range 0.00 to 360.00.

a, d_sp2d_lp 'Short Path km'
Returns 'Long Path km'.

Both are floating point values.

EXAMPLES

Start rotctl for RotorEZ using the first serial port on Linux:

$ rotctl -m 401 -r /dev/ttyS0

Start rotctl for RotorEZ using COM2 on Win32:

C:\> rotctl -m 401 -r COM2

Start rotctl using rpc.rotd and querying the position:

$ rotctl -m 101 -r localhost \get_pos

Connect to a running rotctld with rotor model 2 ("NET rotctl") on the local host and
specifying the TCP port on POSIX:

$ rotctl -m 2 -r localhost:4533

and on Win32:

C:\> rotctl -m 2 -r 127.0.0.1:4533

DIAGNOSTICS

The -v, --version option allows different levels of diagnostics to be output to stderr and
correspond to -v for BUG, -vv for ERR, -vvv for WARN, -vvvv for VERBOSE, or -vvvvv for
TRACE.

A given verbose level is useful for providing needed debugging information to the email
address below. For example, TRACE output shows all of the values sent to and received
from the radio which is very useful for radio backend library development and may be
requested by the developers.

EXIT STATUS

rotctl exits with:
0 if all operations completed normally;
1 if there was an invalid command line option or argument;
2 if an error was returned by Hamlib.
