If this adapter uses a cable to adapt a standard DB9 to the Mac DB8  
then you can likely use it with OS X. You'd need to determine the  
chipset used in the adapter and then find an OS X extension for it.  
You can probably plug the adapter into the USB and look in System  
Profiler to see about the chipset. It may be a Prolific Logic PL-2303  
which has OS X drivers.

Maybe. As I recall there's a hard-to-find (Belkin? MacAlly?

I have a G4 Cube and PM G4 MDD both boot OS9 and I use a program to

I have been using an old Mac SE/30 for that kind of thing. OS 7.5 talks to OS 
10.3.9 quite well on ethernet but you can't use Tiger. With OS 9 you'll be fine.

But you should be warned that RS232 has been modified in usage more or less 
recently. USB to RS232 converters, especially those that use power from the USB 
bus at +5 volts claim to be RS 232 compliant but they are not  if you read the 
RS-232C standard which is all I can afford.

The problem is that the new stuff doesn't go negative to represent a mark 
(logic 1) condition. It just goes low enough, about +100 mV, to look like a 
logic low to a modern CMOS gate.  Your CNC machine or hub may well requite a 
voltage below -3 V which is the RS 232C standard. Mac serial ports are fine 
with that. I have also used a 1.5 volt dry cell in series with the TxD data 
line polarized to subtract 1.5 volts from the fake RS232 signal from the 
USB->RS232 converter.

Something else I find useful is a cheap Intel box that's just good enough to 
run Linux and still has serial ports. Linux is comfortable with OS-9 and all 
versions of OS neXt over Ethernet. If you're willing to  learn some perl have a 
look at . It goes the other 
way, reading from an oscilloscope over RS-232 but might be a starting point.

Re: USB to serial??

[admin]

Back when USB was first introduced and serial ports nom longer  
included companies came out with Serial to USB adapters.  Should still  
be around.  I remember needing an ethernet interface to make something  
like a laser printer still work, but I don't think you will be  
overloading the information capacity of the link.  Good luck.

I stand corrected - they don't have any plans on supporting Mac,
however I thought since OS X is based upon BSD it would have support.

I tried a Belkin that I have for printers that never did work even on the 
printers so I'll try the keyspan. The problem may go deeper because the I/O 
program requires selecting a port for transfer, the only choices that are 
given are printer or modem, so any idea how that may work?
