TERM SUBCOMMANDS
f. 1 /PREVIOUS
FUNCTION:
Display the previous screen (page).
DESCRIPTION:
In TERM mode, a screen (page) portion (8 lines x 2 screens) can be
maintained as screen display. Only the second screen (page) can be
displayed normally, however the lines that disappear from the screen
due to scrolling are sent to the former first screen (page).
The PREVIOUS command is used to view the lines (up to eight) just
before they disappear from the screen by scrolling.
Press the f.1 Key in TERM mode to allow the first screen (page) to
be displayed. Press the f.1 Key again to return to the second screen
(page). The first screen is used for display purposes only, as data
communication is not allowed here. Any keys input will cause the
return to the second screen.
When the first screen is displayed, any data received is stored in the
buffer and the operation to write into the second page is not
performed. If communication is performed without being con¬
trolled by an "x" parameter, data is accumulated in the buffer and
any overflow will be lost.
