Hello Vasile, Am not using serial lib with interrupts. Maybe I need to use that lib. Current problem is GSM modem seems to acknowledge (ex: "OK") faster than my code can read it... A simple "AT" seems to get the "OK" faster than I can read. And I want to get all acknowledges... to not step to next AT command before having sure of "OK" response from the modem. All my AT commands to send an SMS are working ok, if no checking for the acknowledges... Big battle here under going. :D Thank you for your input.
