245503 - DOC: fix for PR#243845 skewed text in chatdiag manpage
245504 - Performance enhancement in the transmission cycle

245931 - Hex field in image definition will not allow A-F hex characters
246136 - obeyfile stop causes chat board to go OFFLINE
246447 - Read sub-channel address cannot be changed dynamically
246622 - Hard reset will not clear "white button" diagnostic mode
246687 - Chat board does not come back ONLINE after LPAR IPL
ATTENTION During the IPl of the mainframe, the CHPID to which the Channel Attch board is connected, is taken offline. This will cause the board also to go offline. A fix has been made that automatically tries to bring the board online. This attempt is made every 15 seconds until the online operation is successful.
When the mainframe comes up, if the interval - from the time that the CHPID is configured online and the corresponding 3172 devices are varied online - is less than 15 seconds, then the varying online of the devices will fail since the Channel Attach board will still be offline.
247168 - Spell check on error message from chat
The alternate configuration file option (-f) option to chatadmin(1M) and chatconfig(1M) is not supported.
Workaround: None.
The chatconfig utility accepts incorrect values without doing enough checking.
Workaround: There is no workaround for this problem in this release of the product. ptx/ADMIN handles input validation before invoking chatconfig(1M) to update the configuration file.
When running on a STiNG 1 multiquad, in a quad other than quad0, the board will run for a short time, then its state will go OFFLINE.
Workaround: This problem has been isolated to the firmware that gets downloaded to the Channel Attach board. Until the new firmware is delivered, Channel Attach boards must be placed in quad0 on a STiNG I multi-quad system.
The transmit and receive buffers of ptx/Channel Attach are statically allocated during the system boot time. Even though the kmstune(1M) utility lists the per-structure memory allocation pools from which the ptx/Channel Attach buffers are allocated, the number of these buffers cannot be altered using kmstune(1M) while the system is up and running.
