Assuming the setup is the same as every other sparc machine I've seen,
you don't have extra serial ports you can use for tty's (sorry).

The motherboard has 2 `zs' Zilog serial controller chips, each of
these has two serial ports. The first controller gives us the tty
ports (zs0a, which you'll be using for console - check dmesg for
confirmation, and zs0b). The second controller is used for the
keyboard and mouse, if attached.
