Assuming I don't need a driver for my USB to serial adaptor cable, are you saying the command you gave me ls /dev/cu.* Will give me a list of devices, and I should be able to find the name of my cable from the list? And then I could run the command echo "text" > /dev/ttyUSB0 Substituting ttyUSB0 with the name of my cable? I am currently trying to figure out how to login as root user, so I can run the echo command to test my synthesizer. Thanks for the help so far, btw when my USB to serial cable is plugged in, I can go to the apple menu then more info and under USB there is a lot of info, like it says: USB-Serial Controller It also mentions the name of a driver and it also has pci device Id: 0x2831 I don't know if that means anything, or not?
