CH6-CH0 - Defines the character vertical height, which is programmable from 18 to 71 lines. The char-
acter vertical height is at least 18 lines if the contents of CH6-CH0 are less than 18. For
example, when the content is " 2 ", the character vertical height is regarded as equal to 20
lines. If the contents of CH4-CH0 are greater than or equal to 18, it will be regarded as equal
to 17. See Tables 2 and 3 for a detailed description of this operation.
