Differences between direct shell login and 3270 terminal support.
(1) You cannot switch to SO/E. However, you can use the TSO SHELL command to run a TSO/E command from your shell session.
(2) You cannot use the ISPF editor (this includes the oedit command, which invokes ISPF edit).
(3) You can use the UNIX vi editor, and other interactive utilities that depend on receiving each key stroke, without hitting the Enter key.
(4) You can use UNIX-style command-line editing.
