DISCONN CP Privilege Class: Any Use the DISCONN command to disconnect your terminal from the VM/370 system while the virtual machine continues operation. The format of the DISCONN command is: +----------+------------------------------------------------------------------+ | DISConn | [HOld] | +----------+------------------------------------------------------------------+ where: HOld specifies that the communication line is not to be disabled. This option allows you to disconnect your terminal, and, at the same time, to avoid the process of telephone dialing into the system to access your virtual machine again. If specified, control returns to CP and the "VM/370 online" message is displayed. Usage notes: 1. The terminal remains disconnected until it is reconnected via a LOGON command. The virtual machine is logged off 15 minutes after an attempt is made to read from the terminal or if the virtual machine goes into a disabled WAIT state. The user should be aware that certain operating systems frequently issue "reads" to the console, which can cause the logoff time-out situation. 2. If your terminal connection is broken because of terminal, line, or teleprocessing control unit errors, CP places the virtual machine in disconnect mode for up to 15 minutes and your virtual machine does not continue to run. If you log on within 15 minutes, your virtual machine can continue operating. Since many operands of the SET and TERMINAL commands default to OFF when you log on again, you have to reissue the SET and TERMINAL commands. If you do not log on within the 15-minute interval, the virtual machine is logged off. 3. Unless the CP command, SPOOL CONSOLE START, is issued to spool the virtual console output, all "writes" or output messages to the virtual console are ignored. When the terminal is reconnected via the normal logon procedure, the terminal is placed in CP console function mode. To resume execution of the virtual machine, enter the BEGIN command. Response When the DISCONN command is issued, the disconnect time message is issued. DISCONNECT AT hh:mm:ss zone weekday mm/dd/yy is the response to the user who issued the command. GRAF raddr ยฆ LINE raddr ยฆ DEV resid DISCONNECT userid USERS = nnn is the response to the primary system operator informing him that the user represented by userid has been disconnected from the VM/370 system. The response, nnn, is the total number of users remaining in the system. DEV resid indicates the resource identification of a 3704/3705 line.
