[Soekris] Connecting to a net4521 from Mac OS X

As others have mentioned, there are a lot of ways to do the Mac to  
4521 connection. I have yet to find one that *does not* work on the  
Mac for basic communication.

There is one thing to be careful about. The ComBios serial flash  
update uses Xmodem-CRC. The process the bios uses is "tuned" to match  
the Windows Hyperterminal implementation of the protocol. I have had  
odd things happen with a couple of programs, both on Windows and the  
Mac. I have not chased down the issues, I just switch over to  
Hyperterminal when I'm doing an update.

As long as you are not doing flash updates, you should be ok with a  
*lot* of different programs.
