IBM 3708 Description page 194

DEC VT220:
The DEC VT220 can generate escape sequences that are too long for
the standard terminal table. To support these longer sequences, the VT220 terminal
table has a fourth section that occupies addresses X'118' to X' 12B'. These
addresses contain the hex function numbers for each of the VT220 keys that generate
long escape sequences (see Table 4-17). The 3708 recognizes this extended terminal
table only when bit 4 of address X' 002' is set to 1 and there is a X' 7F' in the
address for the first character after the X' IB5B' introductory sequence. (Because
the VT220 is an ANSI X3.64 terminal, the left bracket (X' 5B ') is considered part of
the introductory sequence is ignored.)
