^A ^D COMMAND
101 Send User RAM Available: The printer will send the number of free or
available bytes to the serial port (i.e. >192480<).
Use the D119 command for more detailed reporting.
XX 104 Save ASCII Fonts to RAM: The ^Axx specifies which memory file # (CGN #)
the FONT will use (1-255). This command should be used with an ASCII-HEX
file that contains only printable characters less than 80 HEX. These FONTS
are “extended non-compressed”, meaning that they can be greater than 64KB
in size. This command supports fonts greater than 64KB.
XX 105 Delete Graphics from RAM
^A0 deletes ALL graphics from RAM.
^Ax deletes the graphics in slot #x.
xxyy 107 Save Compressed GRAPHICS to RAM.

119 Display Memory Allocation.
This command shows how all of the RAM and FLASH memory is being used
Example display from the ^D119 command:
Ram Based Fonts/Graphics(TCI=8) - [file number(CGN), size, type]
[2,4625, Font set]
 Slot #2 in RAM has a FONT that is 4,625 bytes .
Ram Based Formats - [file number, size]
[2,176]
 Slot #2 in FORMAT RAM has a FORMAT that is 176 bytes.
Total Ram Memory Available - 258335  There are 258,335 bytes of RAM available .
Flash Based Fonts/Graphics(TCI=7) - [file number(CGN), banks used, type]
[1,1, Graphic]
 Slot #1 of FONT flash has a GRAPHIC that takes up 1 bank (64Kbyte)
Font/Graphic Flash Memory Banks Available - 119  There are 119 banks of 64KB open.
Flash Based Formats - [file number, size]
[1,176]
 Slot #1 of FORMAT flash has a FORMAT file that is 176 bytes.
Format Flash Memory Available - 65359  There are 65,359bytes of FORMAT flash open.
Label Memory - [size, available]
[43231,41618]
 The difference is the amount of memory to process current format.
NOTES: RAM GRAPHICS can extend beyond the starting slot # into
sequential ones. RAM formats are numbered #1 to #128 (RAM FONTS are
limited to 64K in size.)
122 Display Available FONT/GRAPHICS FLASH memory.
This command is used to display the amount of FONT/GRAPHICS FLASH
memory available in bytes in the form >xxxxxxx< where xxxxxxx is the number
of available bytes.
