setserial ttys0 error???

**JockVSJock** · 09-23-2003, 12:54 PM

Keep getting this error message

Code:

ttyS0:  LSR Safety Check Engaged

Did some googling and found that if I run

Code:

set serial /dev0/ttys automatic

This takes care of that error message.

BUT, if I reboot, I have to do this
all over again.

How do I fix this one time?

thanks

Can you disable PnP in your BIOS? Post the output of lsmod please.

Why do you think it may be PnP? It was working fine, then I apt-get and it loaded a package and boom, getting this error message.

thanks

For some reason, I was missing serial.conf under /etc.

I got a copy from another Knoppix user and rebooted and all is fine know.

BUT, I have no idea why it was deleted.

Interesting. I've routinely disabled serial and parallel ports on my machines since I have no need for either. However I was receiving the same warning "ttyS0: LSR Safety Check Engaged" until I went back into the BIOS and enabled the ports. Knoppix evidently does not like a disabled serial port.

**hemps** · 12-11-2003, 09:22 PM

Please post the serial.conf file so we can see how to write
Thanks

**niederberger** · 01-18-2004, 05:40 AM

yes please. If anyone have a proper serial.conf, or the proper solution to the "ttyS0: LSR safety check engaged" problem on a system without serial ports (my notebook for example), please email "nieder at mail dot ru".

Thanks

When this happened, I was running Knoppix V3.2.

Can't remember why, but I blew it away and did a fresh install of Knoppix V.3.3.

Either way Knoppix is a sweet distro, and not having any problem with tty, but if it happens to anyone, get a serial.conf file and replace what you have. It fixed mine.

thanks

i think that's my problem. I don't have a /etc/serial.conf.
Could you send yours to the email "nieder at mail dot ru" ?

I tried disabling all serial support on the kernel, but that didn't help either.

Thanks.

Tried to PM you, but looks like it ain't working.

Anyways, sent you serial.conf.

Here is the thing, I don't see it for V3.3, so I took it off of my Slackware 9.1 box.
