Very Computer

Many thanks for your answer about the settings for hyper terminal
to connect my windows box over the serial port with my sun ultra 10.

9600 bps, 8 data bits, No parity, 1 stop bit, XON/XOFF flow control

I also set "diag-switch? = true" but I'm still not able to get the
data transmitted to my hyper terminal session.

Does it debend on which serial port (ttya or ttyb) I connect the
Null Modem Cable on the Sun Ultra 10?
Does it just send the data over the serial line when there is no
keyboard connected?
I still want to have my keyboard connected if possible.
Maybe after all, my cable is not working fine.

But thanks for your help.

Yes - you need to connect to TTY A.  (Try no flow control)
BTW, Hyperterm is known to be a bit iffy for this sort of
use (though I can't recall the details).

Yes.

If you want a serial console, you have to remove the keyboard.
The OBP uses the presence of a keyboard (or lack thereof) to
determine where the console is.

The default configuration of Solaris does not enable a login
service on either serial port.

If the machine is powered on without a keyboard attached, it
will automatically switch the system console to serial port A.
When this happens the console login service runs on serial port A.

So you have a choice.  Power on the machine without the keyboard
plugged in so the console login service is automatically run on
serial port A, or enable a login service on serial port A (or B)
yourself.

To enable a login service using Admintool:

 1. log in as root, run admintool
 2. choose Browse->Serial Ports
 3. click once on the "a" line or the "b" line - whichever one you
    plugged the serial cable into.  Clicking highlights that line
 4. choose Edit->Modify
 5. in the next window, set the Template button to "Modem - Bidirectional",
    then to "Terminal - Hardwired"
 6. make sure the "Baud Rate" button is 9600
 7. type vt100 in the "Terminal" text box
 8. click the "OK" button (not the "Apply" button)

you're done.

no, you do NOT want XON/XOFF flow control.

either set flow control to 'none', or 'hardware' if you have a full
null-modem rather than a cheapie one.

You DO have a nullmodem adaptor, I hope.

Phil, knee-jerk reactions are how myths propagate.

XON/XOFF is what the Solaris serial console uses by default.
Without ANY indication that totaliwok wants to transfer files,
XON/XOFF is a perfectly fine setting.

do you have any references for this?

All I've found so far is
http://docs.sun.com/?p=/doc/805-0429-10/6j0fk0fvi&a=view
 [and similar pages]

which does not reference flow control at all.
(which to me, implies 'none')

Log into a Sparc through the serial port, type "stty -a" and
notice the ixon parameter.

Or look at the /etc/ioctl.syscon file (it's in stty -g format).
