NOTE

An 8 x 14 font for mode 55h is provided with a DOS TSR (terminate and stay

 

resident) program. If the TSR has not been loaded when the mode is set, the

 

8 x 16 font is used with the two bottom rows deleted. This causes truncation

 

of characters with descenders, but does not restrict program operation nor

 

does it make characters particularly difficult to read. For absolute

 

compatibility with some DOS applications that use the 8 x 14 font, the TSR

 

should be used.

 

It should also be noted, that some modes are not supported by all monitors.

 

 

The fastest refresh rate for that particular monitor type selected is

 

automatically used.
