I am a beginner and for the first application I have downloaded in to a Q2501 a program that is occupying all the time the RS232 interface by sending all the time data.
So, now it is not possible, at my level of competence to download something other in to the Q2501.
Somebody may help me be indicating which is the way to erase the program memory, or to stop the application, or some other procedure ?
At the begin, before to download the “bad” application, I hade the answer AT, Enter, OK , but after download, there is no comunication available.
Thanks in advance
