I found ser2net but from what I was reading it looks like it is for
an Ethernet device to connect to a serial port of the Linux machine.
The Ethernet and/or USB would be implemented on a PIC processor so

Defintely serial->usb. (It actually depends on which specific brand but
many are supported.)
I haven't seen built-in support for serial->ethernet, but ser2net is a

serproxy is the same ser2net but using raw, instead of telnet protocol

it don´t allow baud rate, rts, etc

Hmm, it does currently work with ser2net and a passive adapter (within the
same machine or across a very fast LAN).
I can't find much information on serproxy. What happens when you try it?
Optimally unrecognized telnet options should be ignored.

owfs does support telnet (RFC2217) control of the serial port for most
of the serial adapters.
It was tested with ser2net.
For example, with a DS9097U adapter, instead of
/opt/owfs/bin/owserver -d /dev/ttyS0
do
/opt/owfs/bin/owserver -d 192.168.1.23:10001 # assuming that's the

Hi!
I'm using self-made DS2480B serial adaptors and got hold of a
Serial-to-Ethernet (TCP/IP) box (Precidia Ether232). Is anybody here using
such a box together with owfs (owserver)?
The box listens on a freely defined tcp port to forward data between the
PC and the serial device.

Yes. It's the"passive" adapter and is fully supportted and works well

Hi,
I see your problem, but on the other side you have all motherboards with PCI

SMBus controllers but no generic I2C host chips. And most of these are already

Hi,
Besides more restrictive electrical specifications and timeouts to prevent the

this is not true the other way around. Because of this it wo
That's OK. There is so little actual i2c code, I can use the raw i2c commands.
Near as I can tell, there are only a few primatives:
DeviceReset
1W reset
1W channel select
1W read/write byte
1W triplet
1W powerbyte
Some things, like selecting i2c address, and distinguishing between -100 and
-800

Hi,
as far as I remember the header file which is supposed to be used with
userland programs is distributed as part of the the lm-sensors source package
as it is needed also in the sensors-detect program.
