Scrolling Margins (Top and Bottom)
The scrolling region is the area of the wireless station’s dis-
play that can receive new characters by scrolling old char-
acters off the display. The area is defined by the top and
bottom display margins (Table 8-24). The smallest scrolling
region allowed is two lines. The number of the top margin
must be at least one less than the number of the bottom
margin.

Printing
Select print operations with control sequences (Table 8-25).
When characters are printed on the screen, printer tab
stops are ignored. Print characters are spaced with the SP
character. The wireless station sends a carriage return and
line feed, vertical tab, or form feed after the last printable
character on a line (not a space character).

NOTE: The wireless station ignores printer port DSR exchanges.
