UPDATE: No keyboad input through serial port
2007-12-24 21:52:00
Richardson and Ken Zachmann suggesting that I set my OBP
input-device and output-device values to ttya . I forgot to mention that I
had already tried that .I am using a win 2000 laptop to connect to the
serial port A of
the SUN E220.
The E220 has a graphics card ,so I could change the eeprom settings of
input/output device to ttya ; On reboot ,I see the output correctly directed
to the hyperterminal window of the laptop instead of the console screen, but
it doesn't accept any keystrokes from the laptop. I had to do a stop-N to
reset the nvram settings
so that I could redirect the output back to the console screen and accept
entries from the local keyboard.
The E420 does not have a graphics card , so I can't even do a break to
bring to the ok prompt since as I said no keyboard strokes are sensed .I
even tried
Teraterm and procomm plus but ,no luck.
By the way , I checked the eeprom settings on headless systems that I
have,and all systems show output-device=screen and input-device=keyboard
,But
I can still plug my laptop to the port A and it works fine .

Subject: No keyboad input through serial port
Hello Managers,
I am trying to connect to a SUN E220R serial port A using Hyperrterminal .
When I boot the system I can see the output in the hyperrterminal
Window ,but it doesn't accept any keyboard input . The Null modem cable is
ok ,since with the same setup (9600 ,8,N,1) and this cable ,it
works on other E220s and Netras.
The OS is Solaris 8 with latest patches.
I have a similar problem on a E420R .The only hardware change I did was to
take out a Ultra SCSI diff card from the E420 and put it in the E220.
I don't know how that would be related to this problem.
Any ideas ?
Thanks
Pravin
