I’m trying to get a serial port on my Mac to send G code to my Bridgeport CNC mill.
I just got my USB to RS-232 DB9 serial adapter and it shows up after installation of the driver on my Mac (MacBook Pro i7, OS X High Sierra).
The problem I have is that when I go into System Preferences>Network>USB Serial Controller-D>Advanced
and select Null Modem
The lowest baud rate available in the pulldown menu is 9600 bps.
Unfortunately, the mill CNC control only supports 4800bps, 7E1
Am I just out of luck and will have to try using an old Windows laptop or something?
Thanks in advance!
