Hi
thank you for response
7,8 software serial, 9 on/off switch, but if i use other pins situation is the same. i notice that including "newsoftserial.h" blocks Ethernet library even without gprs board. Now i'm using mega 2560 with Ethernet shield and gprs shiled connected to one of additional serial channel (rx1/tx1) directly to gprs jumper switch by a cabled patch. it run good but sound like a trick...
