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