Hit "break" key on console and now can't type anything

[Steve_615]

To all:

I hit the "break" key on the HP serial connected console and now can no longer type. I tried cntl b,c,d Tried powering on terminal while holding "d" key for default reset. Nothing is helping. Must be a simple combination of keys....I just don't know what they are. Any suggestions on how to unlock this keyboard after hitting the "break key".

Thanks in advance for any help

Hi,

Try Cntl & q key at the same time.

Steve,

Can you ssh into the system and kill the running console session?

Hi Steve,
Just check whether the REMOTE tab seen below the terminal screen is selcted.
If not it would get disconnected.
TO select it use F4 funbction key (if REMOTE TAB is not displayed then use F8 key to go into configuration mode).
Hope that helps.

I can not telnet to the system, that's why I happened to be at the console.

The "remote" tab does have the * on it so it should be o.k.

Cntl Q did not help.

Thanks for your suggestions........anyone have any other ideas. It was working fine until I hit the break key by accident. I have it unplugged at this point hoping some kind of timeout will reset the port or something.

Thanks,

Steve

at one time the break key was used to change the baud rate of the getty processes.

don't know if this is your situation, but you can give it a try.

if this is the case, when you first hit the break key the getty process changed it's baud rate. So, now the terminal and the computer are at different baud rates. And, the computer no longer understands anything you type.

each time you hit the break key the getty process will change to the next defined baud rate. I think the console default has 4 baud rates defined, maybe more.

Anyway, the good thing is once you reach the last defined baud rate, hitting the break key will cycle back throught the defined rates again starting at the first one.

So, just hit the break key and type for a bit. if still nothing, repeat. you might have to do this 10 times. if it takes more then 10 i don't think that is your problem

Hi,

Cntl+q in the start key combination by default & is required to start followed by stop through break or cntl+s. Allthough you can set it in profile. Possibally your start sequence is altered through profile. If you have some running session then try giving "stty -a"
speed 9600 baud; line = 0;
rows = 24; columns = 80
min = 0; time = 0;
intr = ^C; quit = ^\; erase = ^H; kill = ^U
eof = ^D; eol = ^@; eol2 = ^@; swtch = ^@
stop = ^S; start = ^Q; susp = ^Z; dsusp = ^@
werase = ^@; lnext = ^@
parenb -parodd cs8 -cstopb hupcl cread -clocal -loblk -crts
-ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl -iuclc
ixon -ixany ixoff -imaxbel -rtsxoff -ctsxon -ienqak
isig icanon -iexten -xcase echo echoe echok -echonl -noflsh
echoctl -echoprt echoke -flusho -pendin
opost -olcuc onlcr -ocrnl -onocr -onlret -ofill -ofdel -tostop

It will display your current key set, try that.

Best of Luck.

Hi Steve,
You should have star on REMOTE tab.
Go to configuration and select remote by F4 function key to see star on that TAB.
Let me know if it works.
