You need to read separately. The write to driver command does just 
that. If you check "the result" after a write, you will be able to see 
if there was an error:

	-- sendEOL = LF or CRLF or ASCII(13) or it may be empty
	-- thePort = /dev/cu.XXXXXXX (whatever the address of your device is)
	write theData & sendEOL to driver thePort
	if the result is not empty then answer the result

After that, you need to read from the device using a command like:

	-- recEOL = LF or CRLF or ASCII(13) or it may be empty
	read from driver thePort until recEOL

I set up a reading loop which is basically this:

on readPort
	read from driver thePort until recEOL
	if it is not empty then put it after fld "recField"
	send readPort to me in 5 ticks
end readPort

This continuously reads from the device and logs any returning 
messages. Try something like this with various settings for sendEOL & 
recEOL.
