Hi,
I want to setup pppd to connect a Linux laptop to an embedded Linux
device. The Linux box connected to a rs-232 to rs485 converter, then the
convert connected via a two-wire rs-485 cable to the embedded Linux
device's rs-485 port.
I firstly started pppd command on the embedded device like as below:
pppd nodetach noauth nocrtscts 192.168.2.1:192.168.2.2 /dev/tts4 38400
then I started the pppd command from the laptop:
pppd nodetach noauth nocrtscts /dev/ttyUSB0 38400
But I cannot get it with success. Blow are the outputs from the
embedded device:
-------------
using channel 11
Using interface ppp0
Connect: ppp0 <--> /dev/tts4

-------------
On the otherhand, I can make success with similar commands when two
devices connected with rs-232. So I guess, this failure was because the
rs-485 is half-duplex. But I searched google, people seemed say pppd
should work over a point-to-point rs-485 connection. So I want to get
help from your experts.
Thanks in advance.
