<strong>MTS</strong> 4: <strong>Terminals</strong> <strong>and</strong> <strong>Networks</strong> in <strong>MTS</strong><br />

July 1988<br />

The cursor must be moved to a nonprefix position before typing can<br />

proceed.<br />

Suspending _________________ Output<br />

The PAUSE key, located in the function pad, can be used to suspend<br />

the transmission of output to the terminal. When output is suspended,<br />

the PAUSE key will light up. The PAUSE key can be pressed again to<br />

resume the transmission of output. If the terminal is in PAGE mode (see<br />

description of PAGE mode), output will be suspended when a full screen<br />

has been received <strong>and</strong> displayed. Pressing the PAUSE key allows the next<br />

screen to be received <strong>and</strong> displayed. Pressing the ATTN key will cancel<br />

the effect of the PAUSE key <strong>and</strong> simultaneously generate an attention<br />

interrupt.<br />

Line ____________ Reentry<br />

In addition to typing in the input area, a user may enter a line<br />

already displayed in the window by moving the cursor to the desired line<br />

<strong>and</strong> pressing the RETURN key. All characters in the line containing the<br />

cursor will be written in the input area <strong>and</strong> then transmitted to the<br />

system. Note that any characters already in the input area will be lost<br />

when this is done. If the line to be reentered is not entirely<br />

displayed on the screen, the terminal will automatically append undisplayed<br />

parts before the line is moved to the input area <strong>and</strong> sent to the<br />

system.<br />

Any line on the screen can also be edited before it is transmitted.<br />

If an attempt is made to insert characters in a line that is longer than<br />

80 characters, the line will be written in the input area where<br />

insertion can be continued. These features allow the user to easily<br />

correct an input line that was rejected by the system. For example,<br />

consider the following portion of a terminal session:<br />

┌─────────────────────────────────────────────────────────────┐<br />

| #edit mylib |<br />

| :atler@a@nv /f ’ABC’123’ |<br />
