PC机接收部分编程：PC串口的RTS经电平转换与PTR2000无线MODEM的TXEN相连。
计算机要发送数据时，RTS变为逻辑1有效，也即PTRZ000的Pin7(TXEN)被置为1，
此时可发送数据。计算机接收数据时，RTS逻辑0有效，也即PTRZ000的Pin7
(TXEN)被置为0，此时可接收数据。PC机接收部分程序介绍如下：-PC-receive part of programming: PC serial port' s RTS by PTR2000 level conversion and the TXEN connected wireless MODEM. Computer to send data, RTS to logic 1, the effective, or PTRZ000 the Pin7 (TXEN) was set to 1, can send data at this time. Computer to receive data, RTS effective logic 0, or PTRZ000 the Pin7 (TXEN) was set to 0, to receive data at this time. PC-to receive some of the procedures described below:
