hello,
i need to write an application for an arm-linux sbc to interface with
a device over rs-485. it is just point-to-point communication and doesn't
use any of the multipoint communications ability of rs-485.
could anyone pls. tell me where i can find information about linux and
rs-485?
thanks in adavnce,
Deva Seetharam

Re: linux and rs-485

Use the standard serial protocols that are used on rs-232 ports and
you will do just fine. The RS-485 standard specifies the hardware that is
used and not the communications protocol. RS-232 is more susceptible to
noise than RS-485 and RS-485 can be used over greater distances than RS-232.
