Date: 18 Jul 97 16:20:43 GMT Organization: York University, Ontario, Canada Lines: 18 Message-ID: <rreiner.869242843@nexus.yorku.ca> Reply-To: rreiner@fscinternet.com NNTP-Posting-Host: nexus.yorku.ca Xref: euryale.cc.adfa.oz.au comp.sys.sun.admin:90155 comp.unix.admin:60691 comp.unix.bsd.netbsd.misc:6281 Scenario: old SparcStation 1+ box. Running NetBSD. CG6 framebuffer driving ancient Sun monitor. Monitor *died* and cannot be resurrected. Replacement cost of monitor very high relative to value of system. Proposed solution: use serial console. Problem: how to switch sparc 1+ to serial console (with any reasonable but *known* serial port parameters) -- without seeing what I'm doing. Request: boot PROM keystroke sequence to accomplish the above blindly. First keystrokes will of course be 'n ENTER' to enter 'new' mode in the boot PROM ... and then what? Alternate request: any other solution to above situation. Many thanks, Richard
