Fedora Hardware :: How To Mount Serial Port?

Sep 24, 2010

I think I need to mount a serial device, but not sure how. I looked at /etc/fstab, but cannot determine what to put in for the mount type. And, not sure what port it would be exactly... imagine either "ttyS0" or "tty0". Can someone give a newbie some guidance on how to possibly mount this device?

General :: Windows With Putty Via USB Serial Cable To Serial Port - Output Ok, Input Isn't?

Jan 13, 2010

I am trying to get two way serial communications going between a Windows XP system and a Linux system (RHEL 5).I have /sbin/agetty -L 9600 ttyS0

in /etc/inittab. I am using a generic USB to serial adaptor on Windows (Unitek) and a null modem cable. I have putty configured for 9600 baud, 8 bits, no parity, one stop bit, no flow control.I get the login prompt from agetty in the putty window but input does not work; I see weird characters in the putty screen. I can echo output into the device from windows and see it, but

cat < /dev/ttyS0. just prints out weird characters from what I type.

Fedora :: Change The MOBO And Trying To Get The Serial Port Working?

Apr 20, 2011

I've just had to change the MOBO and trying to get the serial port working, I see from previous posts there are some problems lurking in the past.

setserial -g /dev/ttyS*
/dev/ttyS0, UART: 16550A, 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

but I'm not seeing anything from a GPS receiver in NMEA at 4800 no par 1 stp I know that was working about a year ago. I think udev was not helping ,as I was getting permission denied to the com port, I added myself to group dialout. and no message on startup now

I need to be able to talk to a piece of kit with 9600 baud and nothing. I have win32 s/w to drive it , but it falls over in wine. My laptop still has win7 on it in a tiny partition but no 9w d connector and I'm waiting for a USB converter cable. Too many variables ! I'd forgotten all the hassle of having to install drivers just to get basic things running. But as the stupid thing couldn't manage using the driver for my NIC, I was stuck with hyper-terminal, and nothing from the GPS board @4800 or another piece of equipment running at 9600. I suspect the com port on the new mobo doesn't wan to play

Fedora :: Connecting Cisco Console Port - USB To Serial Converter

Dec 16, 2009

I am trying to connect to a cisco console port using the usb to serial converter. I am using minicom and I changed me setting to reflect the USB converter cable, but it isn't working. I have set my baud rate to 9600, 8 data bits and no parity. Minicom acts as if it is connected (it doesn't give any errors), but there is nothing on the screen and nothing happens when I type. Also, I use the tail command and it sees the usb connector connected when I unplug it and plug it back in.

Software :: Resetting A Serial Port ?

Mar 23, 2009

I communication with different subsystems using serial port. In some subsystems after running for a while, I start getting invalid data inspite of system sending correct data. For dealing with this situation I used to
reset serial ports by closing and reopening serial port, it was doing the trick but somehow when I have implemented this in my new application, this also doesn't work.

void CPort::

The ClosePort function invokes close system call.

some other way to reset serial port in Linux? I am using RHEL 4, C++ and Qt 4.2.1 for my application development. Also I have used multithreading to implement each subsystem in a separate thread. Its strange that if A,B,C are three threads, A & B run fine together but when C is introduced B starts receiving invalid data after sometime and never recovers even after resetting the port as mentioned above.

I'm using C serial in a program to open and use a serial port but the port won't open for one reason or another. The program successfully runs on a different computer and when using RealTerm: Serial Capture Program, I can connect through the serial port with the same settings as I'm attempting through my c code.
