The Modem and PC interface is the interface circuit of the Modem's single-chip microcomputer W77E58 and the PC, the W77E58 supports the TTL level, and the microcomputer serial communication interface RS 232C supports the EIA level, so you need to design the level conversion circuit when you are realizing the serial communication between them to meet their needs. The level conversion circuit is the interface circuit of the command center modem and the microcomputer, it is also a part of the wireless data transmission system hardware circuit (command center).
