Symptoms:
	PHNE_18773:
	SR None / DTS TPO0h01967
	Some ports on some 8-port cards fail to come up in X.21
	mode.

	SR None / DTS TPO0h02414
	A customer would like to be able to configure the
	frame protocol buffer transmit timer in the same
	way timers are configured in HDLC-LAPB.
	A problem exists at baud rates of 1200 and below.
	A full buffer of data (238 bytes) will be cut
	short when the 1 second transmit timeout expires.

	SR None / DTS TPO0h02504
	With the baud rate incorrectly configured as 64,000
	while the actual line speed is 9600, transmitted
	frames can be cut short and joined together.

	SR None / DTS TPO0h02773
	Some ports on some cards do not work properly in X.21 mode
	on the 8-port NIO and EISA cards.  Some of these failures
	occur just after a card reset, and recover after some 10 -
	30 seconds.  Other ports fail all the time.  The failure
	appears to be the port detecting the CTS and/or DCD signals
	missing.

	PHNE_15594:
	SR 4701391862 / DTS TPO0h01966
	No current method to determine hardware revision

	PHNE_14054:
	SR None / DTS TPO0h01833
	8-channel NIO card crashes, with the use of the frame
	protocol and hdlcabm protocol together on the same port.

	SR None / DTS TPO0h01640
	2 channel ACC card transmits a bad frame at the
	beginning of link setup.

Defect Description:
	PHNE_18773:
	TPO0h01967
	Change to ensure that X.21 is disabled for the Z7200A Rev.A
	card only.  Change particularly focused at the Z7400A EISA
	cards to ensure that Rev.A cards are not disabled from X.21
	configuration.  This corrects the X.21 configuration problem
	with all cards.

	TPO0h02414
	The transmit timeout is fixed at 1 second which
	is not enough to allow the complete transmission
	of a full buffer (238 bytes) at 1200 baud or less.

	The frame module now sets the timeout according
	to the configured baud rate on the port.

	Baud rate        Tx timeout (x100ms)
	   300                 136
	   600                 69
	  1200                 35
	  2400                 18
	  4800                 10
	  9600                 6
	 >9600                 4

	These timeouts allow approximately double the
	necessary time for the maximum of 252 bytes to
	be transmitted.
	252 bytes is the maximum number of bytes to be
	transmitted because that is the maximum which
	can be held in one ACC buffer.

	TPO0h02504
	This is due to an enhancement that was made for
	defect TPO0h02414.  The transmit timeout used at
	level-1 was shortened for baud rates as high as
	64000.

	Because incorrect baud rate configurations can
	lead to this problem, part of the changes made
	for TPO0h02414 have now been backed out.
	The minimum timeout used is now 1 second which
	will allow for typical incorrect configurations.

	TPO0h02773
	The Sipex chips (line drivers) when placed in RS422 mode
	(balanced signaling mode used for X.21) leave some unused
	TTL output pins in an unknown state.  These pins are used
	for the CTS signal when the Sipex chip is in RS232 mode.
	The firmware was reading the state of the CTS signal - and
	the ISCC chips were configured to react to this signal.
	This problem was not detected before because the usual state
	of these Sipex pins signal that CTS is up.  On some Sipex
	chips, this signal is down, or is down and then comes up
	after a short period of time after being put into RS422
	mode.  The firmware has been changed to ignore the CTS
	signal when in X.21 mode.  Also the ISCC chips are
	configured to also ignore changes in the CTS and DCD
	signals.  The firmware code still checks the DCD signal -
	which matches the X.21 Indicate signal, so the firmware
	still can detect a cable disconnect.  Note:  There is no
	problem in ignoring the (internal) CTS signal - as it does
	not map to any signal in X.21.

	PHNE_15594:
	SR 4701391862 / DTS TPO0h01966
	Enhancement to detect hardware revisions of ACC cards.
	A standard interface has been defined to identify hardware
	revisions of all ACC cards.  The 'mx' command of zmntr has
	been enhanced to include
	the display of the hardware revision.

	PHNE_14054:
	SR None / DTS TPO0h01833
	Firmware failures with FRAME and HDLCABM concurrently
	in use.

	SR None / DTS TPO0h01640
	2ch card transmits bad frame on link startup

	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHNE_18773

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHNE_18773.depot

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHNE_18773.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	WARNING: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHNE_18773.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHNE_18773.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	SUBSYSTEM_SHUT
	After installing this patch, the ACC subsystem must then be
	stopped and restarted using zmasterd in order to download
	the new firmware.
