Abstract
A data transmission system includes a first data terminal equipment, a first modem, a transmission line, a second modem and a second data terminal equipment connected in series. In order to send a control command to the second modem, the first modem interrupts a path of transmission data from the first data terminal equipment to the transmission line. Then, the first modem sends the control command to the second modem. When the second modem detects the control commands, it interrupts a path of receiving data from the transmission line to the second data terminal equipment to avoid a dead-lock of the data transmission system.
