Hardware :: Change Serial Port Settings?

Mar 18, 2009

I am using Fedora 10 and I need to change the defaults that get set on the serial port.I know how to do what I need to in Windows, but I can't seem to figure it out in Linux.

Windows Settings:
Bits/Second '115200'
Data Bits '8'
Parity 'None'
Stop Bits '1'
Flow Control 'None'
Receive Buffer 14 (HIGH)
Transmit Buffer 16 (HIGH)

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

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.

Ubuntu Networking :: Change The Proxy Settings And Put In The IP Address And Enter The Port To 3000?

Nov 8, 2010

My college providers shifted to a different setting.. I'm not sure what needs to be done. On windows, under the connections tab you need to change the proxy settings and put in the IP address and enter the port to 3000. Questions:

1. where lies the linux (ubuntu 10.04) variant to execute the operation.

2. What can be the major obligations of such a change?

I am sure its siimple enough, but I can't get my net to work properly. The connection provided to the internet is through wireless routers.

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.

Programming :: C - Serial Port Won't Open?

Sep 1, 2010

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. Anyone have any idea why it might be failing? I know this is still pretty vague, so let me know if there's other things I can tell you that might help to finding a solution

Ubuntu :: How To Login On Gnome/X Via Serial Port

I'm writing a point-of-sale application in Perl/Tk, to run on Ubuntu. For cashier accounts, I plan to just use normal Linux accounts. Cashier login will be done by scanning a badge with a barcode ID on it. Our barcode scanners are older serial-port types.
