knew it had to be possible to view serial data in the OSX terminal window, but I’m not enough of a unix geek to figure it out. Finally, a little googling told me what I needed to know. Here’s how to read and send serial data from the terminal in OSX.<\/p>\n

For example, my list looks like this:<\/p>\n And I know from previous experience that \/dev\/tty.Keyserial1 is my Keyspan USB-to-serial adaptor. It’s connected to a PIC at the moment. The PIC’s programmed to read one byte of serial data at 9600 bits per second, then send back three bytes, “A”, “B” and “C”. Then I started typing bytes at the PIC, and it sent bytes back to me. Whee! No need for zTerm!

\nFirst, open Terminal. If you’ve never used it before, it’s under Applications\/Utilities\/Terminal. Next, type<\/p>\nls \/dev\/tty.*\n<\/pre>\n
\/dev\/tty.BTRS232 \/dev\/tty.Tigoe6630-AppleAgent-1\n\/dev\/tty.Bluetooth-Modem \/dev\/tty.Tigoe6630-Dial-UpNetwor-2\n\/dev\/tty.KeySerial1 \/dev\/tty.modem\n<\/pre>\n
\nKnowing the serial port, you can just type screen portname datarate to show the serial data on the screen. In my case, it was:<\/p>\nscreen \/dev\/tty.Keyserial1 9600\n<\/pre>\n
