C++之AT指令与GPRS通信 - c++编程基础

rn nDst; } void Gprs::on_Btn_Cancle_clicked() { QString tmp=ui->Txt_TargetNum->text(); int i=tmp.length(); ui->Txt_TargetNum->setText(tmp.left(i-1)); } void Gprs::setNum(QString str) { /*if(this->focusWidget()==ui->Txt_HostNum) { ui->Txt_HostNum->setFocus(); ui->Txt_HostNum->setText(ui->Txt_HostNum->text()+str); }*/ ui->Txt_TargetNum->setText(ui->Txt_TargetNum->text()+str); return ; } void Gprs::on_Btn_zero_clicked() { setNum(0); } void Gprs::on_Btn_One_clicked() { setNum(1); } void Gprs::on_Btn_Two_clicked() { setNum(2); } void Gprs::on_Btn_Three_clicked() { setNum(3); } void Gprs::on_Btn_Four_clicked() { setNum(4); } void Gprs::on_Btn_Five_clicked() { setNum(5); } void Gprs::on_Btn_SIx_clicked() { setNum(6); } void Gprs::on_Btn_Seven_clicked() { setNum(7); } void Gprs::on_Btn_Eight_clicked() { setNum(8); } void Gprs::on_Btn_Nine_clicked() { setNum(9); } void Gprs::on_Btn_Cancle_2_clicked() { ui->Txt_TargetNum->clear(); return ; } void Gprs::on_pushButtonNew_clicked() { setNum(NEW); } void Gprs::on_pushButtonAll_clicked() { setNum(ALL); } void Gprs::on_pushButtonCall_clicked() { if(fd>0) { QString DialNum=ui->Txt_TargetNum->text(); if(DialNum.length()==0) { ui->Txt_State->setPlainText(You should put num!); return; } else { QString DialCommand=ATD+DialNum+; ; MySerial::nwrite(fd,DialCommand.toLatin1(),DialCommand.length()); } } } void Gprs::on_pushButtonUnCall_clicked() { MySerial::nwrite(fd,ATH ,sizeof(ATH )); }
