section 5. Format of CP Commands 71

DISCONN Use the DISCONN command to disconnect your terminal system while the virtual machine continues operation. DISCONN is:
from the Vf1/310 The format of the r 1 DISConn r 1 I L 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 "Vf1/370 online" message is
displayed.
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 operatinq systems frequently issue "reads" to the which can cause the logoff time-out situation.
2. If terminal connection is broken because of terminal, line, or TP unit errors, CP places the virtual machine in disconnect for up to 15 minutes and your virtual machine does not
continue to run unless SET FUN ON has been previously specified.
If on within 15 minutes, your virtual machine can continue operating. since many operands of the SET and 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 loqon procedure, the terminal is placed in CP console
function mode. To resume execution of the virtual machine, enter
the BEGIN command. When the command is issued, the disconnect time message is
issu ed. DISCONNECT hh:mm:ss zone weekday mm/dd/yy
is the response to the user who issued the command.
