Read RS232 send to KNX Group adress

[admin]

Are you sure that data is being sent to the port? Try this and post what you get in Logs tab.

Code:

if not port then
  require('serial')
  port = serial.open('/dev/RS232', { baudrate = 9600 })
  port:flush()
  line = ''
end

char, err = port:read(1, 60)
log(char, err)
