CMS Terminal Interface 71
Invoking and disconnecting from the CMS terminal interface
Input lines
Support is provided for two modes of operation: line-at-a-time and full-screen
support. In line-at-a-time mode, when Model 204 is prepared to accept input, it
issues the appropriate prompting character and unlocks the keyboard. After
entering an input line, the user indicates that the line is complete and transmits
the line by pressing the Enter or Return key. In full-screen mode, the user
presses Enter to transmit the contents of the entire screen. The full-screen
mode of operation is described in “Full-screen formatting” on page 9.
PF keys
Program Function (PF) keys are supported by Model 204 only when the user
accesses a screen formatted through the User Language full-screen formatting
feature. Otherwise, PF keys are not supported and cannot be used to enter
data. Any line entered by means of a PF key is considered null, and any data
entered is lost.
Disconnecting
To disconnect, follow these steps:
1. Log out of Model 204 in the normal way by entering either:
LOGOUT
or:
LOGOFF
These commands can cause an automatic disconnect to occur.
2. If an automatic disconnect has not occurred, enter:
DISCONNECT
or the disconnect sequence for the installation.
CMS displays the Ready message.
Turning off the terminal
If the terminal is turned off during Model 204 processing, subsequent
operations depend upon the type of terminal used.
If Model 204 is accessed in full-screen mode, the power-off condition is not
detected until the terminal is turned on again. At this point, z/VM forcibly
disconnects the user and starts a timer. After 15 minutes, unless the user
reconnects to the virtual machine, the user is logged out of Model 204.
Model 204 detects the logout and restarts.
