Capture Calculator Screen
The screen image of the calculator can be captured into a graphic window in Debug4x. This window is automatically placed on the Windows clipboard ready to be copied into a graphics application.
The calculator provides this ability through its printing capability. It thinks that Debug4x is an HP graphic printer.
To use Screen Capture:
If Screen Capture Does Not Work
On the HP-48, flag -33 must be cleared and flag -34 must be set
on the calculator. Enter 33 +/- PRG TEST NXT NXT CF and 34 +/- PRG TEST
NXT NXT SF to do this.
On the HP-48, when the ROM XSEND or XRECV commands are used, the printer is blocked from the serial port. When you press right-shift then 1 nothing happens on the screen (the little sending annunciator in the upper left of the screen does not appear).
This will happen after downloading the XSRVR, for example, because the internal XRECV command is used.
Do a warmstart to clear the problem: hold the ON key down while you press and release the C key, then release the ON key.
Running any of the commands (including HELP) from the new XSRVR library will also clear the problem. The new XSRVR library does not have the problem from the ROM.
