No. 262 Wait for DSR (Data Set Ready) 2006-05-25

I have a weather station software, connected to the ez200F that waits to get DSR = 1, but it never receive this signal and then send a 'Connection timeout'

Does ez200F needs to have a specific configuration to receive this signal ?

Thanks
Christopher
ps : below a part of the code
