And how i can delete those errors from buffer or reset the cp340? without stop-run the cpu. My big problem is that the factory working 24hours the day and i cant stop the cpu. When i stop-run the cpu, the CP340 works fine, the buffer is cleanedbut for a couple days, after 10 or 15 days or 2 months(it is no periodically)the buffer is full and i cant receive nothing. How i can avoid this annoing error?? There is any command to clean the buffer? Please Hellp!!!! Thang you guys Attachment cp340.JPG (143 Downloads)
