Re: Connecting to Sun Ultra 5 over serial line
By the way, in my experiences with Sun, you need hardware flow control enabled. Also, you need to ensure that the cables you are using have all of the pins connected, and you are correct in assuming that you need a null style cable. Occasionally you'll find a crappy serial cable where the hardware flow control pins are disconnected. On my sun's (ultra 10 and ss20), they use the following by default: 8N1 9600 rts/cts

Shame, really. cheers, MC

Hah, well that pretty much settles it - this is a faulty machine. I tried STOP-N on boot, no video and now the machine refuses to acknowledge that the keyboard exists too. Thanks to all who replied.

Instead of using minicom, can you try: # cu -l /dev/cua00 This works fine (here) from and to a Blade 100/SS4/SGI 02. > > When I switch on the Sun, I'm told that I should get some > console output and then the usual ok> prompt.

The output from that command was colourful to say the least and in fact caused xterm to glitch (the prompt was replaced with strange control characters in that strange manner that sometimes happens when you accidentally cat a binary file). No luck so far... MC

It may have to do with flow control settings (should be 'none'), and do you know for certain if the sun console is set to 9600? I have good success with tip(1). It ships with the OS. $ tip -9600 tty00 DS
Connecting to Sun Ultra 5 over serial line
Hello. I'm trying to connect to a Sun Ultra 5 from my OpenBSD laptop (a thinkpad) but I'm currently stuck. I have next to no experience with serial communications, so I'm groping around in the dark currently. I have a serial cable with a null modem adapter connected to the DB9 serial port on my laptop and the DB25 A serial port on the Sun. I'm using minicom, at 9600 baud and using the /dev/tty00 device. When I switch on the Sun, I'm told that I should get some console output and then the usual ok> prompt. I actually get a lot of control characters and binary gibberish. Where exactly do I start with troubleshooting? The cable doesn't seem to be at fault, so I'm assuming that the problem is software related. cheers, MC
