(Most Linux distros never added it to their repos) The single-purpose-tool interceptty from 2006 has slightly simpler syntax, but can only intercept TTYs (while proxying ioctls), and is probably not in your package manager.If you need to setup your serial port, or send other ioctls, do so before calling socat, as socat cannot proxy them.The socat syntax looks confusing at first, but in fact, it's just 2 nested statements.Ī small price to pay to such a powerful, versatile tool.The files in.txt and out.txt will then contain the captured data. SYSTEM:'tee in.txt |socat - "PTY,link=/tmp/ttyV0,raw,echo=0,waitslave" |tee out.txt' Googling "socat serial port pty tee debug" will point you to several "standard procedure" examples, one being: socat /dev/ttyS0,raw,echo=0 \ In your usecase you could connect your serial port /dev/ttyS0 to a PTY /tmp/ttyV0, then point your application to the PTY, and have socat tee out Input and Output somewhere for you to observe.

I like it because it have a full support for colors and UTF and is very tiny if you have miniterm.py -help Python-serial have a utility named miniterm.py. The minicom is used to connect to the device and access BIOS and boot the system: Here is a quick demo of my Soekris router running monowall embedded version. If you forced to use MS-Windows, try the following free and open source serial communication programs: $ man putty A note about MS-Windows users Do read the following manual pages using the man command or help command: You can also use the KVM over IP client as described here for serial console redirection over IP (LAN/WAN). RHEL / CentOS / Fedora Linux: Set a serial console.Debian / Ubuntu Linux: Set a serial console.See our previous howtos about setting and redirecting console output over serial port: $ tip -19200 ttys0 How do I redirect Linux / BSD console output over serial port? tip command can be found under AIX/HP-UX/Solairs/*BSD/Linux operating systems. The tip command is used as a serial terminal. $ sudo apt-get install putty #5 tip command You can use the apt-get command/ apt command or yum command/dnf command to install putty:
