Causes the link to become inoperative
if a start I/O timeout occurs because the receiving host is in disabled
compatibility mode. MIH stands for missing-interrupt handler. The
default time value associated with this operand is 3 minutes, although
you can change the default with the MIHTMOUT start option.
- MIH=NO
- The MIH default of NO means that VTAM® does
not deactivate the link if REPLYTO plus MIHTMOUT time units expire
without receipt of an interrupt.
- MIH=YES
- If MIH=YES is coded on a CTCA LINE statement (or sifts down to
it from the GROUP statement), VTAM deactivates
the link if the following time elapses after START I/O is issued from
the link: REPLYTO (from the GROUP statement, default 3 seconds) plus
MIHTMOUT (start option, default 3 minutes), and no interrupt has yet
been received.
Note: If you do not code MIH, a link can appear active but
is most likely hung or unusable. Therefore, coding MIH=YES is recommended.
