AST 5250 EMULATION WITH DESQVIEW
|
|||
|
|
|
|||
|
|
|
|||
|
|
On page 2-38 of the AST-5250/Emulation Program Base manual (part
|
|||
|
|
number 000425-001), it is specified that "you must remap the 5250
|
|||
|
|
'Error Reset' key, the PC 'Alt' key, to avoid conflict with
|
|||
|
|
DESQview's operation...It is, therefore, recommended that the
|
|||
|
|
"ESC" key be remapped as the "Error Reset" key for a 83/84 type
|
|||
|
|
keyboard. And the "~`" key remapped as the "Error Reset" key for
|
|||
|
|
a 101/102 type keyboard. Both these keys ("ESC" for 83/84
|
|||
|
|
keyboard and "~`" for 101/102 keyboard) will be referred to as
|
|||
|
|
the 5250 "~`" key from now on.
|
|||
|
|
|
|||
|
|
The following procedure outlines the necessary steps needed
|
|||
|
|
to perform the operation:
|
|||
|
|
|
|||
|
|
1. First swap the scan codes for the 5250 "`~" key with
|
|||
|
|
the "Error Reset" key. Both upper and lower case
|
|||
|
|
must be remapped.
|
|||
|
|
|
|||
|
|
a. Go into the REMAP_SC option in the CFG5251
|
|||
|
|
program.
|
|||
|
|
|
|||
|
|
b. Choose key 1 (the PC position for uppercase
|
|||
|
|
"~`") to remap (that position should currently
|
|||
|
|
be BE), change to FE (scan code for uppercase
|
|||
|
|
"Error Reset").
|
|||
|
|
|
|||
|
|
c. Choose key 56 (the PC position for uppercase
|
|||
|
|
"Error Reset") to remap, change to BE.
|
|||
|
|
|
|||
|
|
d. Press Esc to go into lowercase mode.
|
|||
|
|
|
|||
|
|
e. Choose key 1 and change scan code to 7E.
|
|||
|
|
|
|||
|
|
f. Choose key 56 and change scan code to 3E.
|
|||
|
|
|
|||
|
|
g. Press Esc to save changes.
|
|||
|
|
|
|||
|
|
|
|||
|
|
2. Now swap the control functions for the 5250 "~`" key
|
|||
|
|
with the "Error Reset" key.
|
|||
|
|
|
|||
|
|
a. Go into the REMAP_CTRL option in the CFG5251
|
|||
|
|
program.
|
|||
|
|
|
|||
|
|
b. Choose 2 (the Alt control function, should be
|
|||
|
|
38 - the PC scan code for "Error Reset").
|
|||
|
|
|
|||
|
|
c. Enter 1A (dummy scan code, because two scan
|
|||
|
|
codes with the same values are not allowed).
|
|||
|
|
|
|||
|
|
d. Choose 1 (the Esc control function, should be 1
|
|||
|
|
- the PC scan code for "~`").
|
|||
|
|
|
|||
|
|
e. Enter 38.
|
|||
|
|
|
|||
|
|
f. Choose 2 again
|
|||
|
|
|
|||
|
|
g. Enter 1.
|
|||
|
|
|
|||
|
|
h. Press Esc to save changes.
|
|||
|
|
|
|||
|
|
The 5250 "~`" key and "Error Reset" key have now been completely
|
|||
|
|
swapped and will function accordingly. Now to produce an "Error
|
|||
|
|
Reset", just keep the 5250 "~`" key down (which is 101/102
|
|||
|
|
keyboard's "~`" key or a 83/84 keyboard's "Esc" key). To do a
|
|||
|
|
"round-robin" hot-key press <Esc>-<Alt> for 83/84 type keyboards
|
|||
|
|
or <~`>-<Esc> for 101/102 type keyboards. Keeping the Alt key
|
|||
|
|
down will now invoke a DESQview command instead of an "Error
|
|||
|
|
Reset".
