APAR Error Description / Circumvention

-----------------------------------------------
If an Asychronous (ASC) communication line which is not running
under an I/O Processor (IOP) fails to vary on, a subsequent vary
on will result in a CPD27D0, Line already in use, message

CORRECTION FOR APAR MA40665 :
-----------------------------
An incorrect check within the code resulted in the I/O Driver
deactivating, but the code above was left in a state where the
deactivate was still outstanding.



This PTF will be built as an Immediate Apply PTF.



If you do not currently have the problem stated above, for the
code to activate, each communication line must be successfully
varied off then varied on.



If you currently have the problem stated above, this code will
not take affect until after an IPL, since the line can not
currently do a successful vary off.

CIRCUMVENTION FOR APAR MA40665 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
