During console redirection, the remote terminal sends keystrokes to the local server. The remote
terminal may be a dumb terminal or a system with a modem running a communication program,
such as ProComm*. The local server passes video back over the same link.
For keys that have an ASCII mapping, such as A and Ctrl-A, the remote terminal sends the ASCII
character. For keys that do not have an ASCII mapping, such as F1 and Alt-A, the remote must
send a string of characters, as defined in the tables below. The strings are based on the ANSI
terminal standard. Since the ANSI terminal standard does not define all keys on the standard 101
key U.S. keyboard, mappings for these keys were created, such as F5 – F12, Page Up, and
Page Down.
Alt key combinations are created by sending the combination
^[}
followed by the character to
be modified. Once this Alt key combination is sent, the next keystroke is translated into its Alt key
mapping. In other words, if
^[}
is mapped to Shift-F1, then pressing Shift-F1 followed by the
letter ‘a’ would send an Alt-a to the server.
The remote terminal can force a refresh of its video by sending
^[{
. Combinations outside of
the ANSI mapping and not listed in the table below are not supported.
