I had a similar problem with my SS1+.  I don't know what the right
solution is, but I solved it by connecting a few pins of the serial
port so that the CTS input of the port is always active (this gives
the Sparc a permission to transmit data to the port).  Maybe the console
driver always uses RTS/CTS flow control (even if you have no RTSCTS flag
in /etc/ttys)?
