 | | System V releases prior to SVR4 did not support job control or most of the other terminal driver features added by Berkeley. The list of special characters supported by these versions is much shorter: EOF, EOL, ERASE, INTR, KILL, QUIT, and SWTCH. (SWTCH was for System V's layers job control facility, which was abandoned by POSIX in favor of Berkeley-style job control.) | |
