One way to do it:
-- DISCLAIMER: this code is untested --
global gSerialPortData
on startReadingPort
set the serialControlString to tMyPortSettings
put empty into gSerialPortData
open file "COM2:" for read
send "readSerialPort" to me in 100 milliseconds
end startReadingPort
on readSerialPort
read from file "COM2:" until empty
if it = empty then
close file "COM2:"
send "processSerialData" to me in 100 milliseconds
exit readSerialPort
end if
put it after gSerialPortData
send "readSerialPort" to me in 100 milliseconds
end readSerialPort
on processSerialData
-- do stuff to the data in gSerialPortData
end processSerialData
One nice thing about doing things via the "send" command instead of a loop is
that the interface remains responsive to user input while data is being read
from the port.
