MATLAB中通过串口发送手机中文短消息的示范程序

% GB2312 - Unicode 转换表
gut = unitable;

% 输入短消息文字
msg = inputdlg('输入短消息(70个汉字):', 'SMS');
msg = msg{1};
if length(msg) > 70
	fprintf('短消息过长\n');
	return;
end

% 输入对方电话号码
phone = inputdlg('输入对方电话号码(11位数字):', 'SMS');
phone = phone{1};
if length(phone) ~= 11
	fprintf('电话号码长度不对\n');
	return;

% 生成半字节倒序格式的电话号码
phone = ['86' phone 'F'];
p = phone;

% 生成短消息文本
