VT100+ terminal emulation
The VT100+ emulation mode provides compatibility with the Microsoft head-
less server EMS serial port interface. DSView Telnet VT100+ terminal emula-
tion works identically to VT100, with the exception of support for the function
keys listed in the following table.

VT102 terminal emulation
VT102 terminal emulation works identically to VT100 with additional support
for decoding receive codes as described in the following table.

VT102 Receive Codes

cursor position, and moves all remaining characters left n
positions. n spaces are inserted at the right margin.
