Re: Error reading 1-wire

for uart (rs232) without bit bang
can we send for example ! <at> $ASDF$%
and i return FASDLFADSF
just for test? or the protocol is binary (not human) read/writeable?

Re: Error reading 1-wire

I have digitemp installed, I used to use that but changed to owfs so
that I can use i/o as well as temperature.  Next time it happens I will
try digitemp as well.

Thanks

Re: Error reading 1-wire

I would suggest that you move the adapter to ttyS0, which should be the 
built-in serial port with a 'real' UART and see how it works there. 
Eliminate any USB vagueness.

The ttyS2 you are using is USB. I know from professional experience that 
there are differences in USB serial implementations that can cause 
quirkiness. Sometimes the drivers get unloaded, the system goes into 
power saving mode (not necessarily sleep) and powers down the USB 
device, or a number of other things can happen.

If you then move back to the USB serial device and this happens again, 
do a 'lsusb' and make sure the device still shows up. Do a 'lsmod' and 
make sure the kernel module is still loaded.

Re: Error reading 1-wire

Hi Paul,

No it's not USB, I have added a card with two serial ports, so I have
S0, the original port, then S1 and S2 which are the additional ports.

The reason was that on my control PC I am running owfs for 1-wire and
also X10 to drive some outputs, so I needed two serial ports.  In order
to test out stuff I have added a similar card to my desktop and it is
there that I am having these problems, the control PC almost never
stops.

Cheers
Mick

Re: Error reading 1-wire

Hi Mick-

I'm sorry. At first glance the device ID of 03:07.0 looked like USB to 
me., but I guess it's PCI.

I think I'd still start with the basics and make sure everything is what 
it appears to be. Are there any BIOS messages before system boot 
regarding the add-in card? IRQs and IO ports? In the dmsg output are 
there any messages relating to the ports? Anything from 'setpci' or 
'setserial' in the logs?  Is all of this consistent with what is seen in 
/proc/interrupts (activity) , /proc/ioports, /proc/tty/driver/serial ? 
You could also use 'lspci -vv' and take a peek at the card details. I'd 
still look at lsmod after boot when things work. and then again when 
they don't. A lot of this is what you would so if you cant get the card 
to work (which I know is not your problem) but comparing between the 
working and non-working states may show something, especially the 'lspci 
-vv' output.

Usually 16550A UARTS are pretty good, but your's would seem be unhappy 
at times...

Best regards,
Paul

Re: Error reading 1-wire

Hi Paul,

Thanks for the suggestions, I will investigate further next time it
happens.  Always useful to get ideas from experienced linuxers, I am
still learning.
