I managed to solve the problem by redirecting the socat output to a file (which might also be a FIFO if you are interested), and then pointing grep to get the desired line and piping that output to sed to clean the text and get the desired PTY name.

NO!!!, for some reason (still unknown to me) sed and grep got stuck and even if they got the apropriate input they didn't send anything to the screen. The device name is printed to stderr and simply by doing a 2>&1 and pipe it through a sed or awk instance will do the trick. Same as above, still the messages are output to stderr

Once the name is known, attach to the PTY.

Somehow, get the PTY name (the tricky part).

I decided to do some shell magic to automate the task in several steps

Simple shell magic can't work because socat outputs the messages to stderr.

I have to run two commands in order to get the PTY and attach to it (socat, then screen).

The PTY device allocated on Mac OS X is subject to the number of terminals currently being used, so it is a variable device.I wanted to do this as painful (automated) as possible, but there were a few problems: In this case the desired PTY is /dev/tty007 and then in another terminal window

Thanks to this I can happily run the following two commands to attach to the serial consoleĩ 01:08:00 socat N opening connection to LEN=16 AF=1 "./Thesis.ttyS0"ĩ 01:08:00 socat N successfully connected from local address LEN=16 AF=1 ""ĩ 01:08:00 socat N successfully connected viaĩ 01:08:00 socat N PTY is /dev/ttys007ĩ 01:08:00 socat N starting data transfer loop with FDs and I also found a couple VMware forum posts with useful links.

There were some pages describing how to use socat to map a UNIX domain socket to a tty device (actually a PTY). The screen man page describe how to attach to a existing tty device but the file is a named pipe so the program cannot do its magic with it. I tried the nc -U variant as stated in the page but I had no luck making it work because the mac ports version of netcat does *not* support attaching to UNIX domain sockets. VirtualBox (and VMware for what I saw on the pages ) map the serial device of the virtual machine to a "Named Pipe" (actually a UNIX Domain Socket) which can be accessed using netcat or minicom. I normally access a VirtualBox VM serial console through minicom in GNU/Linux, but for some reason it didn't worked on Mac OS X, so I researched about how can I access the serial console.
