Corrected first jump that program makes.

Had to specify the segment in code, and use the offset of pJDosInit.
Changed led output procedure to take parameters.

Added in a delay and now program should flash every other LED every second.
Fixed problem with LEDs not behaving correctly.

Need to always write the fourth byte, even though write
address is given before writing data.
Made better way to invert the bits back and forth.
Adjusted keyread with appropriate scanAsciiTable.

Key scan codes discovered through experimentation, and the keypad layout
was determined. Took out un-used bit in scan.
Changed to a86 supported fast way of changing segment.
Various cleanup and made a splash screen for startup.

Made setup macros to make things more clear during startup.
Added in constants for ram and rom segment.
Made macros into procedures for int21h to be consistent with other interrupts.
Fixed the scan->ascii table.

'A' and 'B' were switched, and also while shifting out the unused bit,
the register was not properly restored.
Started using ramSegment definition.
Cleanup of lcd code is in progress.

It currently works to initialize the keyboard, and you can print characters
one by one to the screen with proper text wrapping.
Need to figure out how to print to memory and then refresh the screen.
Began using div to check for needing to change lcd cursor.

Began using mul to multiply by 20 - cleaner to look at.
Changed the output screen command to a procedure (was a macro).
Added a memory test procedure.

Changed pOutputToLeds to take al as most significant.
Changed first instruction to cli instead of nop.
Various small fixes. Input with echo now calls input without echo.
Now have a working system for basic IO.

Inputs characters and echos them to the screen through the software interrupt int 21h.
Memory Keyboard queue is almost working.
int 10h calls are working well and proper text wrapping has been achieved.
Can input characters with or without echo.
Merge branch 'features/initial-testing' into development
