关于AT指令的编程，请高手帮忙

首先保证ATE!=0

RS232Error =OpenComConfig (com_port_imei,, devicename, 57600, 0, 8, 1, 512, 512 );   // u多了一个逗号
//增加FlushOutQ(comport);
Fmt(write_buffer_imei,"%s<%s","AT+EGMR=0,7\\r");
RS232Error_imei =ComWrt (com_port_imei, write_buffer_imei,strl(write_buffer_imei));  //得到长度的函数错误， strlen();
Delay(0.5);
RS232Error_imei = ComRd (com_port_imei, read_buffer_imei, 30);//把30改成 strlen(read_bufer);
FlushInQ (com_port_imei);
