Module: Net::SSH::Connection::Term

Defined in:

lib/net/ssh/connection/term.rb

Overview

These constants are used when requesting a pseudo-terminal (via Net::SSH::Connection::Channel#request_pty). The descriptions for each are taken directly from RFC 4254 (“The Secure Shell (SSH) Connection Protocol”), tools.ietf.org/html/rfc4254.

37

IXON =

Enable output flow control.

38

IXANY =

50

ICANON =

Canonicalize input lines.

51

XCASE =

53

ECHOE =
