摘要（英）：

A device for switching between a serial port straight-through line and a cross line comprises interfaces and a double-pole double-throw switch. The interfaces include a first interface and a second interface, the first interface comprises a first-interface first end and a first-interface second end, a second interface comprises a second-interface first end and a second-interface second end, the first-interface first end is connected with the second-interface first end or the second-interface second end through the double-pole double-throw switch, and the first-interface second end is connected with the second-interface second end or the second-interface first end through the double-pole double-throw switch. The device is simple, reliable, practical and free of damage to a debugging device, and reliability and efficiency of communication debugging are improved.
