SECTION 8 " Programming
8-46 VT220/ANSI Terminal Emulation Programmer’s Reference Guide
Tests and Adjustments
The wireless station has adjustment patterns you can in-
voke from the host computer with escape sequences. Ad-
justment sequences send uppercase E’s to the wireless sta-
tion’s display. Adjustment procedures are usually done only
by qualified technicians. For more information, contact the
Customer Response Center at the phone numbers listed in
the introduction to this programmer’s reference guide.
Table 8-31 shows the action taken by the wireless station
when it receives test and adjustment sequences.
