Serial Ports with OS X

[Bill Vlahos]

Gene,

Actually there has been a great deal of traffic regarding serial 
communications for OS X on this list. The short answer is that it 
currently doesn't work but that the Rev folks are working on a solution 
which they hope to have in the near future.

Apple is adopting the "unix way" of doing serial ports with the added 
twist that you will need a USB-serial adapter like the KeySpan to 
actually get the physical ports. Apple has made the API's available with 
example code but it won't work or look like older serial communications 
so all previous Comm Toolbox and Open Transport serial calls break in OS 
X. Doing it the "unix way" probably doesn't hurt us too badly as the 
foundation for Revolution (MetaCard) comes from unix.

Serial ports work fine with Revolution under OS 8 and 9 and I suspect 
the Rev folks will get it working under X.
