When playing around with serial ports, I figured why not echo from one terminal and cat/listen from input/output error the other using one of the /dev/ttyS* serial ports on my ubuntu 15.04 laptop. When i do cat /dev/ttyS0 it gives me input output error. then i tried doing it using pyserial on python. when i do import serial ser = serial.Serial('/dev/ttyS0') it gives me SerialException: Could not configure port: (5, 'Input/output error') After looking around on stack overflow, I found this related post Pyserial: could not configure port: (5, 'Input/output error) where one of the guy said you need a physical connection to make cat /dev/ttys1 input/output this happen. I'm guessing that is to create some kind of loop. So my question is what kind of physical connection is required? Who a usb stick do it, or do i need something dedicated to work with the serial port. And if someone would provide good explanation on how serial port programming works, that would be great. Feel free to edit the question where you see fit. Guys please no need to complain about how dumb this question sounds and all that. After all lots of people come here to learn, and that is what i am doing python linux ubuntu serial-port pyserial share|improve this question asked Aug 9 '15 at 20:04 pdhimal1 79212 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote accepted You need to have one or two physical com or serial ports on your pc to achieve this. if you have one port you can create a loopback plug by connectint the Rx and Tx pins together. If you don't have a physical serial port and want to test it you can use scoat to create a virtual serial port. share|improve this answer answered Aug 9 '15 at 20:30 rfkortekaas 1,2251818 ^ thanks, i will try that. Do you mean socat or scoat? –pdhimal1 Aug 9 '15 at 22:43 It's 'socat' see the manpage for details. You can use 'socat -d -d pty,raw,echo=0 pty,raw,echo=0' to create two virtual serial ports. –rfkortekaas Aug 10 '15 at 4:40 worked. Thanks
