Improve macOS Serial Command Instructions
Many of the devices no longer just show "/dev/cu.usbserial" for their path in macOS. For example the SG-5100 with the new serial chipset will show up as /dev/cu.usbserial-[random 4 digit number] when the driver is installed like /dev/cu.usbserial-1540. On the Netgate 1100 the device will show up as something completely different. It would be helpful to adjust the instructions to be more "generic" for macOS. For example, we could direct the users to enter "ls /dev/ | grep cu*" to get the output of all USB serial devices and use that in the screen command.
