串口发送十六进制问题
如何像串口调试助手一样,发送的是FF,接受到的也是FF,而不是63 63 试试 _CommSendString(Chr(63)&Chr(63)) 回复 2# xms77不行
COM2 Write: 2(Byte)3F 1E 本帖最后由 xms77 于 2012-4-10 22:20 编辑
回复 3# lin0308
发送把发送的字符转换成二进制_CommSendString(StringtoBinary("FF")),接受的内容用BinaryToString()试试 回复 2# xms77
发送给单机片的.. 回复 5# lin0308
我也做过发送给单片机的程序,测试成功，系统环境xp sp3，以下代码给你借鉴一下，我也是借鉴别人的代码改的，在我的机器上通讯成功。

你用的是com口检测软件吗？十六进制显示接受到数据呀！ 本帖最后由 hxg123 于 2012-4-24 23:51 编辑
我今天用到了向串口发送十六进制。
如设备地址0x3，控制命令0xa7，我用这个实现了控制。
$Address=3
$Command=0xa7
_CommSendByte($Address)
_CommSendByte($Command)
