Main Keypad
The wireless station emulates all of the standard and most
of the special function keys on the VT220 main keypad.
The standard keys generate letters, numbers, and symbols,
either alone or in combination with other keys. The func-
tion keys generate special function codes.
Table 8-36 lists the codes generated by the special function
keys.
