CoolTerm Module
===============

    A Python implementation of a CoolTerm Remote Control Socket Client

    Requires Python 3

    Roger Meier, v1.6, November 2023


Create a new CoolTermSocket as follows:

    s = CoolTerm.CoolTermSocket()

Alternatively, you may also specify the host IP and Port as follows

    s = CoolTerm.CoolTermSocket("127.0.0.1", 51413)

To disconnect the socket from CoolTerm, use the following

    s.Close()


CoolTermsSocket supports the following commands:

    System commands  
    ---------------  
    Ping as boolean:  Returns True if the remote control socket is connected to CoolTerm.
    LastSocketError as integer:  Returns the last socket error

    Window/App commands
    -------------------
    NewWindow as integer:  Opens a new terminal window. Returns the ID of the new window.
    LoadSetting(FilePath as String) as integer:  Loads connection settings. Returns the ID of the opened window, or -1 if loading was not successful.

    SetBreak(ID as integer, Value as boolean):  Sets the state of the break signal.
    GetBreak(ID as integer) as boolean:  Gets the state of the break signal.

    Text data exchange
    ------------------
    SendTextFile(ID as integer, FilePath as string) as Boolean:  Sends the specified text file. Returns True on success.
    CaptureStart(ID as integer, FilePath as string) as Boolean:  Starts capture of received data to the specified file. Returns True on successful creation of the capture file.
