47 * c_cc characters in the termio structure. Oh, how I love being
48 * backwardly compatible. Notice that character 4 and 5 are
49 * interpreted differently depending on whether ICANON is set in
50 * c_lflag. If it's set, they are used as _VEOF and _VEOL, otherwise
51 * as _VMIN and V_TIME. This is for compatibility with OSF/1 (which
52 * is compatible with sysV)...
