SUMMARY: Screen output via serial connection.

Hello,

Thanks to all that replied. Most replies suggested to set the parameters
output-device to ttya and input-device to ttya. I tried these but they did
not fix the issue.

The solution was provided by Chris H. Thanks Chris..
Here it is..

setenv ttya-ignore-cd true.

This allowed me to see the output..

Thanks again to everyone who took the time to respond..

Hi Sun Managers,

I manage some older SUN hardware remotely. These older SUN machines have no
Service processors. The way I generally connect is to connect a PC to the
SUN box via Null modem cable. From there I remote into the PC and access the
SUN host over serial connection. This works for all of the hosts except one,
which it only works partially for.

By partially i mean the following.
I can control the box from the OK prompt, I can enter OpenBoot commands. I
can power off and boot the box fine.

The problem is that once the OS begins to boot I lose all visual and cannot
enter input anymore. The issue happens whether i boot from the OS disks or
if I boot from CDROM..

I am using the same serial settings that work on other boxes. 9600,8,N,1

Is there something I need to set? Has anyone experienced this.. Very
frustrating because I can do no maintenance..

Below shows where the box gets to when booting, this is when I lose
control..At this point the screen shows no more output. I have to send a
break to get to the OK prompt..


{1} ok  boot cdrom -s
Boot device: /pci@1f,4000/scsi@2/disk@6,0:
f  File and args: -s
SunOS Release 5.10 Version Generic_139555-08 64-bit
