RS485 Extension exposed as Linux serial device ?

[bixator]

Hi,

 

I would like to use the RS485 Master extension as a

Linux serial device (such as /dev/ttyXX) when stacked

onto a RED-brick.

Is there a (brickd ?) configuration parameter which

would allow this ?

Thanks.

An RS485 Extension is already exposed as /dev/ttyS0, but you cannot use it because brickd is using it.

 

So you either need to disable brickd on the RED Brick or patch brickd to be able to use an RS485 Extension as a normal serial port on the RED Brick.

Hi,

 

Thanks a lot for your quick reply.

 

An RS485 Extension is already exposed as /dev/ttyS0, but you cannot use it because brickd is using it.

So, does this /dev/ttyS0 device supports the regular Linux and RS485

specific related ioclt() parameters ?

Any tips to patch brickd for this ? Do you plan to add a brickd configuration parameter which would ease this ?

Thanks.
