SECTION 5 " RT5900 Radio Terminal
VT220/ANSI Terminal Emulation Programmer’s Reference Guide 5-11
Special Function Keys
Table 5-2 describes how to use the radio terminal to do spe-
cial VT220 terminal function operations. Note that the ra-
dio terminal does not support key operation COMPOSE
CHARACTER, which creates characters that do not exist as
standard keys on the VT220 keyboard.
Operation of the delete key depends on how the PROTO-
COL OPTS parameter is set in the radio terminal’s firmwa-
re. The key either sends a delete (DEL, 7F hexadecimal) or
a backspace (BS, 08 hexadecimal).
To change from delete mode to backspace mode, open the
firmware by pressing [BROWN]+[SPACE]. Then select the
following options in this order: SET-UP PARMS (password:
CR52401), PROTOCOL OPTS, VT220, DEL TO BS.
