I got a piece of code written in Python that interacts with different devices through a serial port connection. I usually run in on a Raspberry Pi (e.g. /dev/ttyUSB0 port) or PC (e.g. COM0 port). Currently, I don't have access to these devices, but need to debug the code and only got my MacBook with me. Is there any software that would create a virtual serial port that I can send commands to, and also allow me to monitor exactly what commands are being sent to it? Thanks!
Got a tip for us?

Several possibilities come to mind.
1) Named pipe, aka a FIFO. See man page for 'man mknod 8' or 'man mkfifo'.
2) The pseudo-tty devices /dev/pty* and /dev/tty*. See 'man pty'
3) A Unix-domain socket.
You could also connect a USB-to-serial device to your Mac, which plugs into your USB port. Sparkfun sells such devices with FTDI chips:

There are other sources for similar devices, such as Adafruit.com. The prices can vary widely, as can quality of build and authenticity of the FTDI or other chip.
