程式其中一段
try0: {putrs2USART("ATO+N+0001+001E000000000100\r"); gets2USART(dataa2,2);} if(dataa2[0]=='E' && dataa2[1]=='R') {goto try0;} putrs2USART("ATO+N+0001+A\r"); ........... 當RS232傳輸"ATO+N+0001+001E000000000100\r" 回傳的指令將會有兩種 1為OK 2為ER00 若接收到OK則繼續執行下面的動作 若接收到ER00則跳回try0重新傳輸便式回傳值是否為OK 但是 我測試的結果當收到ER00時將會跳到try0 但卻不會進入IF再一次辨識 卻直接傳送ATO+N+0001+A 是我程式哪裡寫錯嗎?該如何修改? 請先進指教
