The DEVICE Command <strong>CP</strong>/M 3 User's Guide Table 5-4. DEVICE Options Option Meaning XON refers to the XON/XOFF communications protocol. This protocol uses two special characters in the ASCII character set called XON and XDFF. XON signals transmission on, and XOFF signals transmission off. Before each character is output from the computer to the peripheral device, the computer checks to see if there is any incoming data from the peripheral. If the incoming character is XO,FF, the computer suspends all further output until it receives an XON from the device, indicating that the device is again ready to receive more data. NOXON indicates no protocol and the computer sends data to the device whether or not the device is ready to receive it. baud-rate is the speed of the device. The system accepts the following baud rates: 50 75 110 134 150 300 600 1200 1800 2400 3600 4800 7200 9600 19200 Examples: A >DEVICE CONOUT: =L PT ,CRT A >DEVICE AUXIN: =CRT2 [XON , 9600] A >DEVICE LST: =NULL The first example assigns the system console output, CONOUT:, to the printer, LPT, and the screen, CRT. The second example assigns the auxiliary logical input device, AUXIN:, to the physical device CRT using protocol XON/XOFF and sets the transmission rate for the device at 9600. The third example disconnects the list output logical device, LST:. 5-17
