TCPaccess supports both QDIO and IQDIO (Hipersockets). Support for both was added at the same time. Unfortunately the documentation for this configuration is not available in the current manuals but we do have it out on support online.
It is best to start by reviewing a video that outlines QDIO / Hipersocket configuration and where to find all the documentation. It also contains information not included in any of the written documentation. It's only about 20 minutes and many customers have found it extremely helpful.

Below is a current list of PTFs recommended for QDIO / Hipersockets as of September 2010. You may want to check the website in case additional maintenance has been added since then.
Please note that the last few PTFs are also the point at which the PTF numbering changes as TCPaccess has been brought into alignment with CA standards for PTFs, meaning that the numbering is now the same as most other CA products; ROxxxxx. Prior PTFs for TCPaccess all begin with TP.

+ be sure to check the ++HOLD as this PTF adds the PORTNUM parameter required for OSA3.
Since these PTFs span a fairly broad time range, and since all are quite a ways past SP5, we strongly recommend that you apply full maintenance. Applying only the PTFs noted here may require chaining back to SP5, which could result in 'swiss cheese' maintenance that may lead to undesired results.
It is also vital that you cycle the stack with P CLEAR to implement the maintenance as some modules may otherwise not be replaced in storage.
