1 Advanced Communications Controller B.03.32.
What's in This Version The following information applies to version B.03.32.03 of the line of Advanced Communications Controller (ACC) products that are supported on HP-UX 11i. Benefits • This release of the ACC software provides support on HP-UX 11i. It includes fixes that are described in the following section “Patches and Fixes for ACC Version B.03.32.03”. Features and Enhancements • 6 There are no new features or enhancements in this version. Advanced Communications Controller B.03.32.
Known Problems and Workarounds for ACC Products The following lists the known problems and recommended workarounds: • • • You cannot install Advanced Communication Controller (ACC) cards and PSI SDLC cards on the same system. Coexistence of these cards will not work. You can install ACC cards supported by the ACC product or PSI SDLC cards supported by the SNAplus2 product, but both types of cards are incompatible on the same system.
Compatibility Information and Installation Requirements Software Requirements • When compiling application programs that use ACC, use the cc compiler in non-ANSI mode instead of cc in ANSI mode or the ANSI c89 compiler. ACC header files and libraries currently do not support ANSI compilation and linking. Hardware Requirements • Z7340A 8-port PCI Serial card. OS Platform and Version Compatibility • 8 This release supports HP-UX 11i. Advanced Communications Controller B.03.32.
Patches and Fixes for this Version In order to run version B.03.32.03 of the ACC software, the following patches or their superseding patches must be installed. • • PHNE_37671– s700_800 11.11 cumulative ARPA Transport Patch PHNE_36576– s700_800 11.11 Cumulative STREAMS Patch The patches along with the additional information, can be downloaded from http://itrc.hp.com/ The patches are also available from ftp://hpatlse.atl.hp.com/hp-ux_patches/s700_800/11.X/ Defect Fixes in ACC Version B.03.32.
• JAGaf86284 Symptoms: System panics with a Data Page Fault and the stack trace looks as below: panic+0x6c report_trap_or_int_and_panic+0x94 trap+0xf04 thandler+0xd20 N2Z_F0_L_GETSTATS_ioctl+0x268 N2Z_F0_wput+0x2fe0 putnext+0xcc wait_iocack+0x6c str_istr_ioctl+0x2d4 Defect/Fix: The problem happens when x25stat is issued on disabled terminals. This is because the function which gets the status of the terminals does not check whether the terminal is disabled and issues a request to firmware for statistics.

The driver tries to send a connect confirmation, but the connect structures are not filled completely(which is filled when there is an incoming call)causing the system to panic.
condition such as a Reset packet after the timeout. To resolve this defect, code change has been done to check the flowcontrol parameters of the NLI2ZCOM driver. Once the driver is out of the flowcontrol it sends RR.

Defect Fixes in Release ACC B.03.30.00 • JAGad16980 Symptoms: pdisplay runc on ports 2 and 7 of the 2/8-port cards does not work and outputs the following error: Error: Port 7 exceeds the maximum allowed for the card type. Defect/Fix: Whenever you try to use the runc command to configure the last port of any 2-port or 8-port ACC card, the command fails with an error. This defect was caused by a logic error in the port validation code. This defect has been corrected.

The reason for the above problem is that some "break" statements were missing in the switch statement in dsc_card() function of LDM code. It also misses out the setting of "irr.reason" to indicate different reasons for card disable or halt. • JAGad21743 Symptoms: During high load activity on the Z7200A OR Z7400A ACC cards, such as X.25 call establishment and clearing on all port, the port may be unable to accept further transmit requests. The affected port is not usable until the ACC card is restarted.
