/sys$common/syshlp/helplib.hlb SET, TERMINAL, Qualifiers, /PERMANENT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Requires LOG_IO (logical I/O) or PHY_IO (physical I/O) privilege.

    Sets characteristics on a permanent basis, that is, over terminal
    sessions; however, the characteristics revert to their initial
    values if the system is halted and restarted. Use in a system
    startup file to establish characteristics for all terminals on
    the system.
