	NOTE 1:	To get the full support for logical device namespace for 
                printers and new printer minor node type, one needs to
                install the following patches:

		108528-03 (or newer)    kernel update patch
		108979-08 (or newer)    devfsadm, platform nexus, I2C and 
					Netra ct patch
		109880-01 (or newer)    forthdebug patch
		109883-01 (or newer)    ecppsys.h patch

	NOTE 2: In rare cases, the serial lines of the SPC may become 
		hung for no apparent reason.  If this situation occurs, 
		the driver has a mechanism to attempt a recovery that 
		MAY RESULT IN DATA LOSS.  A "deadman" routine can be 
		made to run periodically; if it detects a hung state a
		corrective action can be issued. If you are instructed 
		by Sun support personnel, the following /etc/system 
		variables can be set to control the behavior of the 
		deadman routine:

	stc:stc_deadman_enable  // defaults to 0, if non-zero deadman will be
                        	// run every stc_deadman_timer microseconds;
                        	// otherwise, the deadman will not run

	stc:stc_deadman_timer   // defaults to 15000000 (15 seconds)

	stc:stc_verbose_deadman // if zero, no deadman-related messages are
                        	// printed; if 1 (default), a moderate amount
                        	// of status messages are printed out; if two,
				// even more status messages are printed out.

		If you are not experiencing problems, DO NOT enable the deadman
		mechanism.

		ONLY ENABLE THE DEADMAN MECHANISM IF INSTRUCTED TO DO SO BY SUN
		SUPPORT PERSONNEL.
