I have an Ultra4 system that is hanging during the Power-On-Self-Test (POST). On a Sun keyboard, you can press the "STOP" key to bypass the POST. I use a laptop running Win95 and an emulation program connected to ttyA with no console available. Is there an ASCII equivilent for the "STOP" key?

It depends on the type of terminal emulator you use. For example, TerraTerm (a free, flexible vt100 terminal emulator) has a STOP-A function built into one of the drop down menus (under the Control drop down menu --> Send Break. The short cut key is ALT-B). HyperTerm, the defacto client within Windows, it might be a combination of simultaneously pressed key strokes. The ones I find that seem to work on most non-Sun keyboards are: SHIFT-PAUSE-A ALT-BREAK ALT-SHIFT-A Sorry, I am not aware of any menu choices to effect this on HyperTerm. I learned that the [CTRL] key has it's own interpretations in UNIX, so don't use any combinations with [CTRL]. Combinations with [ALT] usually work. Please let me know how it worked. Good luck.

I can use the SHIFT-break key to issue the "STOP-A" command, but I am trying to issue just the "STOP" command. Any help is appreciated.

Thanks for the help. I found the answer by using a Sun terminal located elsewhere. By generating a bourne shell from within a korn shell, pressing the stop key alone will generate the following string: ^[[23~ This is what need to be programmed into the emulator.

Hi, It is Ctrl+Break to get to the single user mode. After you press Ctrl+Brk, it gives ok prompt. Then type boot -s to get to the single user mode. I tried and it works on solaris Netra-t1-UltraSparc IIi machine.
