Command	:Sg DDD*MM#	5 6
Returns	Ok
Sets the longitude of the currently selected site.
Command	:GG#
Returns	sHH#
Gets the offset from Greenwich Mean Time.
Command	:SG sHH#
Returns	Ok

c. Telescope Motion

Command	:Mn#
	:Ms#
	:Me#
	:Mw#
Returns	Nothing
Starts motion in the specified direction at the current rate.
Command	:MS#
Returns	0, 1, 2, or 4 (see description)

Slews telescope to current object coordinates. 0 is returned if the telescope can complete the slew, 1 is returned if the object is below the horizon, 2 is returned if the object is below the "higher" limit, and 4 is returned if the object is above the lower limit. If 1, 2, or 4 is returned, a string containing an appropriate message is also returned.

Command :MA#

Returns 0

Slews telescope to object alt-az coordinates (set with the Sa and Sz commands). This command only works in the LAND and ALTAZ modes.

Command	:Qn#
	:Qs#
	:Qe#
	:Qw#
Returns	Nothing
Stops motion in the specified direction. Also stops the
telescope if a slew to an object is in progress.
Command	:Q#
Returns	Nothing
Stops a slew to an object.
Command	:RG#
	:RC#
	:RM#
	:RS#
Returns	Nothing

Sefs the motion rate to guide (RG), center (PC), find (RM), or slew (RS).

Command	:Sw N#
Returns	Ok

Sefs the maximum slew rate to "N" degrees per second where N is 2 through 4.

d. Home Position

Command :hS#

Returns Nothing

Sfarts a home position search and saves the telescope position. NOTE: All commands except ":Q#" and ":h?#" are disabled during the search.

Command :hF#

Returns Nothing

Sfarts a home position search and sets the telescope position according to the saved values. NOTE: All

commands except ":Q#" and ":h?#" are disabled during the search.

Command	:hP#
Returns	Nothing
Slews the telescope to the home position.
Command	:h?#
Returns	0, 1, or 2
Returns the home status: 0 if home search failed or not
yet attempted, 1 if home position found, or 2 if a home
search is in progress.
e. Library/Objects
Command	:Gr#
Returns	HH:MM.T#
Gefs object right ascension.
Command	:Sr HH:MM.T#
Returns	Ok
Sefs object right ascension.
Command	:Gd#
Returns	sDD*MM#
Gefs object declination.
Command	:Sd sDD*MM#
Returns	Ok
Sefs object declination.
Command	:Sa sDD*MM#
Returns	Ok
Sefs object altitude (for MA command).
Command	:Sz DDD*MM#
Returns	Ok
Sefs object azimuth (for MA command).
Command	:CM#
Returns	(see description)
Sync.	Matches current telescope coordinates to the

object coordinates and sends a string indicating which object's coordinates were used.

Command	:Gy#
Returns	GPDCO#
Gefs the "type" string for the FIND operation. A capital
letter means that the corresponding type is selected while a
lower case letter indicates it is not.
Command	:Sy GPDCO#
Returns	Ok
Sefs the "type" string for the FIND operation.
Command	:Gq#
Returns	SU#, EX#, VG#, GD#, FR#, PR#, or VP#
Gefs fhe current minimum quality for the FIND operation.
Command	:Sq#
Returns	Nothing
Sfeps to the next minimum quality for the FIND operation.
Command	:Gh#
Returns	DD*#
Gefs the current "higher" limit. \
Command	:Sh DD#
Returns	Ok
Sefs fhe current "higher" limit.
Command	:Go#
Returns	DD*#
Gefs the current "lower" limit.
Command	:So DD*#
Returns	Ok
Sefs the current "lower" limit.
Command	:Gb#
	:Gf#
