Terminal Control
Hard Reset
For the currently active terminal personality, a hard reset has the same effect as turning the
terminal's power off and then back on except that the power-on self-test is not performed.
More specifically, a hard reset does the following:
1. Rings the terminal's bell.
2. Halts any device operations currently in progress.
3. Enables the keyboard (if disabled).
4. Clears all of the workspace.
5. Clears any existing error conditions and removes the error message display (if present)
from the bottom of the screen.
6. Halts any datacomm transfers currently in progress, clears the datacomm buffer, and
reinitializes the datacomm port according to the apprQpriate power-on datacop}m configu-
ration parameters.
7. Resets the terminal configuration menu parameters to their power-on values.
8. Reset the user-programmable function keys to their default settings.
9. Resets certain operating modes and parameters as follows:
Disables Display Functions mode, Caps Lock mode, Report mode, Metric mode, and data
logging.
Resets the left margin to the leftmost screen column.
Resets the right margin to the rightmost screen column.
Thrns off the ((insert character" edit function.
Resets the integral printer, if present.
Clears graphics memory, if present.
From the keyboard, you perform a hard reset by simultaneously pressing the.,
III
and
_
keys. (The IBM personality is not affected by this operation.)
From a program executing in a host computer, you perform a hard reset using the following
escape sequence:
Ec E
Note that hard reset affects only the terminal personality in which it is executed. The
alternate personality is not affected. (Also, an
[c
E,
when entered from the keyboard, while in
IBM mode, will result in an error.)
