The correct settings for talking to a Fujitsu-Siemens Primepower 250 (or a Sun VFire 250, or probably any sun) via the serial console port is 9600 8N1, no software handshake, no hardware handshake.

You know you’re dealing with serious hardware when there’s a setting for altitude in the system configuration. The Primepower 250 uses this setting to calculate how much the fans should rotate for a given system temperature.

Minicom does not handle UTF-8 xterm’s or tty’s very well.. LANG=C is recommended.
