scan_ports ( self )

check all com ports possible for LX connections

test_baud_rates ( self,  portNum )

check com port for possible speeds blist[0] will be the fastest

connect (

        self,

        port,

        baud=9600,

        ptimeout=10,

        )

Opens the port and checks for a telescope - port can be int: [0,...], or alpha: "COMn" - ptimeout>240 recommended for LX200GPS using auto_align

CommandString (

        self,

        cmd,

        *args,

        )

issues a command to the telescope, and awaits a string response terminated by a #. returns string

CommandBlind (

        self,

        cmd,

        *args,

        )

simply packages up command letters in #: # and sends to telescope

__repr__ ( self )

Return a representation string.

set_baud_rate ( self,  baud )

Set Baud Rate n, where n is an ASCII digit (1..9) with the following interpertation 1 56.7K 2 38.4K 3 28.8K 4 19.2K 5 14.4K 6 9600 7 4800 8 2400 9 1200 Returns: 1 At the current baud rate and then changes to the new rate for further communication

CommandBool (

        self,

        cmd,

        *args,

        )

issues command and checks for 0 or 1 response. returns true on success. no hash returned in response.

close ( self )

close the com port

__init__ ( self,  debug=False )

Constructor. Arguments: serial port where the LX200 is connected Note: two ports can be opened on the LX200 - access to the port settings trough Python properties - port numbering starts at zero, no need to know the platform dependant port name in the user program - port name can be specified if access through numbering is inappropriate

if self.debug == True, port reads will return the last command chars, and no scope need be connected

read_to_hash ( self )

reads from port until hash encountered and returns
