>Description:
The getty process running on the serial console (if machine booted without 
keyboard) will force the baudrate to 9600, even if the machine OF console is 
set to 19200.
>How-To-Repeat:
Boot with serial terminal on port A, and no keyboard plugged in.  The sparc 
will put console on serial port.  In OF prompt, set baud rate to 19200 ("setenv 
ttya-mode 19200,8,n,1" IIRC).  Boot freshly installed NetBSD 5.1_RC3. (Or, I 
suspect, many older versions).  Kernel messages will appear normally (at 19200) 
but the login prompt is line noise, until you switch your terminal to 9600.

>Fix:
Delete "sp#9600" parameter from the "suncons" entry:

*** gettytab    Thu Sep  2 11:46:01 2010
--- gettytab.bak        Wed Sep  1 14:59:56 2010
