The first command to ZTERM issues a control request to disable the
ZLUS on the port.
The next request is the ZPORT command. This time, the upper two bits
of the second configuration word must be cleared to indicate RS-232
mode.
The last two commands enable and activate the ports so that they may
be used.

Application Interface

A port may also be put into Loopback mode or RS-232 mode using the
zconfig() ZCOM Programmatic interface request.
• Use the zinfo() request to determine all ZLUs that correspond to a
given port.
• Use the zcntl() request to disable a ZLU. (It can also be used to
re-enable the ZLU after the port mode has been changed.)
• Use the zconfig() or zport() request to change the port mode for a
given MUX port.
Refer to the ACC Programmer's Reference Guide and the man page for
more detailed information about system calls.
Refer to Appendix C, "ACC Service Guard Configuration Notes," on
page 83 for an ACC Service Guard Configuration example that uses the
ZTERM utility.
