This package contains a set of commands to be used with the JBRD shades through utilization of the 'select' function. It also contains two variables: dev_exec and vers

dev_exec: boolean value (default false) that will be changed base upon the most recent execution check
vers: integer value representing the version of the last drive checked

The config file for changing the baud rate and port is found in "./src/config.js"; the default values are: port: "dev/pts/3" baud: 57600

The function takes a set of inputs that determines what commands to send and to what device, all values are taken as STRINGS:

-- NOTE -- the program will accomodate or any missing 0's in device id, so "1" will be converted to "001" automatically before commands are sent.

function select(cmd, dev, ...args)

cmd: the key character that will determine the command to be sent. Possible values:
  "A": abort
    only device number as input 
  "E": immmediate motor halt
    takes device number, deceleration value, hold current, and delay
  "m": execute program
    takes device number followed by the program name
  "r": checks if program execution is in progress
    takes only device number
  "R": drive reset (akin to power cycle)
    takes only device number
  "v": version check
    takes only device number
    

-- Sample Calls --

select("A", "200"); Sends "#200JBRDA"

select("E", "302", "1000", "0.95", "0"); Sends "#302JBRDE1000,0.95,0"

select("m", "401", "FullExtend"); Sends "#401JBRDmFullExtend"

select("r", "609") Sends "#609JBRDr" and changes value of 'dev_exec' according to response

select("R", "1"); Sends "#001JBRDR"

select("v", "108"); Sends "#108JBRDv" and changes 'vers' according to response
