[Solaris] Setting the console serial port Solaris 10

As fan of serial port consoles on my Sun SPARC servers, I do get fedup with slow console baud speeds.

Setting console to 19200,8,n,1 on Solaris 10

Change console speed in the eeprom
$ eeprom ttya-mode=baud-rate,8,n,1,-

Set the console for ttymon
$ vi /etc/ttydefs
console:19200 hupcl opost onlcr:19200::console


Repace /kernel/drv/options.conf with the following
# 19200 :be:
ttymodes="2502:1805:be:8a3b:3:1c:7f:15:4:0:0:0:11:13:1a:19:12:f:17:16";
