MPE/iX NOTES
The mesg utility is currently implemented on
MPE/iX as a call to the MPE/iX SETMSG com-
mand. As a result, it has the same behavior as the SETMSG command. For more information
about the
MPE/iX CI SETMSG command, refer to the MPE/iX Commands Reference Manual.
Executing
mesg n
disables messages from write, wall, and the MPE/iX CI TELL command. It uses the MPE/iX
CI variable HPQUIET to determine the current status.
For more information on how the current
MPE/iX implementation may affect the operation of
this utility, see Appendix A, MPE/iX Implementation Considerations.
