Addressing Hardware - particularly usb port

[Phil Davis]

Hey Peter,

Is your device listed in the output of this function? If so, try opening 
it and writing a command to it.


function myDeviceNames
  # Handler courtesy of Ken Ray & Dar Scott
 
  local theNames="", ioregOutput, skipLines, temp
  local IOTTYDevice, IODialinDevice, IOCalloutDevice
  set the hideConsoleWindows to true
  put shell("ioreg -n IOSerialBSDClient") into ioregOutput
  repeat forever
    put lineOffset("IOSerialBSDCLient",ioregOutput) into skipLines
    if skipLines is zero then return thenames
    delete line 1 to skipLines of ioregOutput
    -- Get all the data between the braces
    put char(offset("{",ioregOutput)) to (offset("}",ioregOutput)) of 
ioregOutput into temp
    get matchText(temp,"\"IOTTYDevice\" = \"(.*?)\"",IOTTYDevice)
    if it is not true then next repeat
    get matchText(temp,"\"IODialinDevice\" = \"(.*?)\"",IODialinDevice)
    if it is not true then next repeat
    get matchText(temp,"\"IOCalloutDevice\" = \"(.*?)\"",IOCalloutDevice)
    if it is not true then next repeat
    put IOTTYDevice,IODialinDevice,IOCalloutDevice & lineFeed after theNames
  end repeat
end myDeviceNames
