AL character to write
BL (graphics modes only) foreground color number

Returns: (none)

Info: Writes the specified character to the current cursor position and
updates the cursor position. When the cursor advances to the end
of the last screen line, this scrolls the text up one line.
This writes the character only. It is displayed with whatever
video attribute is currently at the cursor position. Also, when
the screen scrolls, it fills the next line with the current
attribute of the lower-right corner of the screen.
This function treats these characters specially:
CR (0dH) ─── cursor to start of next line
LF (0aH) ─── cursor to current clm on next lower line
BEL (07H) ─── beep the speaker
This is too slow for most apps. See Video Memory Layouts.
