Cat /dev/ttys0 Input/output Error
up and rise to the top cat /dev/ttyS0 Input/output error up vote 2 down vote favorite I created infrared receiver as in LIRC manual (http://www.lirc.org/receivers.html). And tested it on windows using program called Terminal. When I switched on RTS pin DCD pin was also switched on and when I used remote controll DCD was blinking. So everything works with hardware. Next I tried using the same hardware on Linux Mint 17 on same could not open port /dev/ttyusb0: [errno 13] permission denied: '/dev/ttyusb0' computer as in http://lifehacker.com/5527752/control-your-desktop-pc-with-a-remote-using-lirc but with no luck: piotrek-H87-HD3 piotrek # cat /dev/ttyS0 cat: /dev/ttyS0: Input/output error I also followed http://www.commandlinefu.com/commands/view/10218/ttys0-terminal-on-serial-connection. In this tutorial there was the same error I had so I tried looking in BIOS setup but serial ports were enabled. Why isin't it working? Some information data: piotrek-H87-HD3 piotrek # cat /proc/tty/driver/serial serinfo:1.0 driver revision: 0: uart:16550A port:000003F8 irq:4 tx:0 rx:0 1: uart:unknown port:000002F8 irq:3 2: uart:unknown port:000003E8 irq:4 3: uart:unknown port:000002E8 irq:3 4: uart:16550A port:0000F080 irq:19 tx:34 rx:0 CTS|DSR|CD 5: uart:unknown port:00000000 irq:0 6: uart:unknown port:00000000 irq:0 7: uart:unknown port:00000000 irq:0 8: uart:unknown port:00000000 irq:0 ... //EDIT I was wondering lately if maybe linux somehow switched pin layout of my serial port? My motherboard COM port pins layout is : I have back panel extension cord which maps 1:1 pin layout from motherboard to back panel like this: ------------------- \ [1][3][5][7][9] / \ [2][4][6][8] / \ ___________ / In windows pin order is same as in motherboard manual. Is it possible that pins are switched somehow? Can I check it? Nobody seems to know the answer so maybe I ask another question. Can I write some script (python maybe?) that will enable selected pins on /dev/ttyS0 so I could measure voltage and check which pin is which? tty cat serial-port serial-console sha

When playing around with serial ports, I figured why not echo from one terminal and cat/listen from 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 http://stackoverflow.com/questions/31908335/serial-port-dev-ttys0-and-ttys-input-output-error 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 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 o

Im new to this forum and very new to linux. Im running: Fedora 11. kernel-PAE.i686 (had to install this to get ndiswrapper to work) My problem is: I cant get the serial ports working. They are working under windows vista, so they cant be disabled in BIOS (i guess) The command setserial -g /dev/ttyS* gives the output: /dev/ttyS0, UART: unknown, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3 /dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4 /dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3 and according to this page that means that th
