Description: 本程序采用异步方式，除了可作为一般串口调试程序（232方式，或485、422主）来使用，也可以作为485、422设备（从模式）进行调试，当选中（是否比较）复选框后，收到上位机请求时，如果和比较区的内容一致，则自动回复发送区的内容，未选择比较框将按照设定的发送周期定时回复。
参数设定：
发送周期：单位毫秒。用于设定两次自动发送的时间间隔。
延迟接收时间：单位毫秒。推荐仅用于485方式，因为485为半双工模式，所以不能同时进行收发，此时间间隔在自动发送时必需小于上面设定的发送周期。
限制：发送接收必须为同一进制（十六进制或ASCII等）-err

Description: 单片机和PC机的串行通信一般采用RS-232、RS-422或B3-485总线标准接口，也有采用非标准的20nnJL电流环的。为保证通信的可靠，在选择接口时必须注意：(1)通信的速率；(2)通信距离：(3)抗干扰能力；(4)组网方式。本文主要介绍采用RS-232接口与单片机通信的方法-MCU and PC machines generally use serial communication RS-232, RS-422 or the B3-485 standard interface bus, also have the use of non-standard current loop 20nnJL. To ensure reliable communications, the choice of interface is important to note: (1) communication rate (2) Communication distance: (3) anti-jamming capability (4)组网方式. This paper mainly introduces the use of RS-232 communication interface with the single-chip approach
