TTYA Input and Output

Hi All,

I am new to this forum as well as new to SUN.

I tried to boot a Sun Blade 100. The message that appears on the screen is Keyboard not found. use ttya Input and Output.

I have only a normal MS Keyboard which cannot be connected to SUN. Do we need to have a special Keyboard. Whether we have to use USB Keyboard...

I just want to know more about TTYA input and output.

Thanx.

Hello.

You cannot connect a PS/2 keyboard to the Blade. However you can connect a standard PC USB keyboard to the Blade; you do not need to use a Sun keyboard. I use a cheap USB PC keyboard on my Blade 1000 (not 100).

TTY I/O is done using the serial line. You need a second computer that has a serial port as well as a null-modem connection cable. On the other computer you'll have to run an RS232 software like Hyperterminal. This mode is typically only used for system maintenance of servers (that have no keyboard or screen connectors).
