Classification: openSUSE Product: openSUSE 11.4 Version: Factory Platform: x86-64 OS/Version: openSUSE 11.4 Status: NEW Severity: Critical Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: vrnb05@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:2.0b12) Gecko/20110222 Firefox/4.0b12 Hi, I am using OpenSuse 11.4 distro on Intel's I7 processor and motherboard. It doesnot have onboard serial port, hence we are forced to use USB to Serial converter. There is no error codes that gets displayed on screen. I am connecting through /dev/ttyUSB0 using PL203 driver. When i connect this to my hardware's console, and then execute 'find /' from my hardware's terminal, i get intermittent output thrown on minicom. As and when do keypress or move a mouse pointer it throws up a screenful of output before it stops. Again i have to keep moving either mouse/do key presses on keyboard to get the console output from my hardware. I am unable to get contineous console output of my hardware(logs). On further experimatation, I have found that it doesnot look to be a minicom issue here. I tried using 'screen /dev/ttyUSB0 115200' and 'putty' (for linux) both are showing the same erratic behaviour mentioned above. My tty configuration as optained from stty is as below: root# stty -a -F /dev/ttyUSB0 speed 115200 baud; rows 0; columns 0; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 5; -parenb -parodd cs8 -hupcl -cstopb cread clocal -crtscts ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr -icrnl -ixon -ixoff -iuclc -ixany -imaxbel -iutf8 -opost -olcuc -ocrnl -onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 -isig -icanon -iexten -echo -echoe -echok -echonl -noflsh -xcase -tostop -echoprt -echoctl -echoke root# uname -a Linux srinirao 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 x86_64 x86_64 x86_64 GNU/Linux Has anyone came across this issue ?
