[Ham-Mac] OS X contest, TNC software help

[Greg & Kris Palfe]

Hello all,
I just got onto OS X with a new iMac 17 inch macnine.  I came from 9.2 
G3 desk top using MacRatt and Marathon with the PK232.

With OS X I cannot use PK232 as MacRatt and Marathon have communication 
requirements not supported by X or now by even running 9 classic.  
MacRatt and Marathon both look for modem ports and there is no way to 
fake it with OS X even using a USB-serial adapter into the Mac.  The 
apps still want to see modem or printer ports.

Does anyone have any suggestions how I can get back into my PK232 so I 
can run the digital modes and run the Marathon contest program?  Or, 
are there other contest and TNC apps that will run on OS X that I do 
not know of?

Thanks,
Greg, wa0bnx
