Mode 55 will use a 16 dot high font, with the bottom two lines truncated, in the absence of the 8x14 font
TSR (TSRFONT). The characters "g," "j," "p," "q," "y," and "ÿ" are truncated using a middle and bottom
line algorithm to avoid truncation of descenders. For compatibility with some DOS applications which
use the 8x14 font, the TSRFONT utility should be used.

A character "i" stands for interlaced mode. 43.5 Hz or 87 Hz interlaced.
