>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

 suncons does not sound like a good choice for serial console anyway...

 Probably true - but atm the user cannot specify this at install.  Is
 there any reason for getty to force a baudrate change if on a
 "default" console?  (I also notice that sp#9600 is in the Xwindow
 entry as well)
 The miniroot install works on 19200 without problems since getty is not use=
