Linux PPP
2003-03-12 11:16:36 UTC
Hi all,
am currently working on PPP over serial interface (RS485) in linux 2.4.2-2. I believe RS485 half duplex system and hence only one can transmit at a time. And for RS485 we basicaly use Master-Slave or Primary-Secondary kind of communication. I don't know how to achieve the same using PPP since i need to have max of 10 nodes connected via serial interface. I tested with two nodes using PPP daemon it works fine. Following are the commands i issued
In PPP server:
$usr/sbin/pppd -detach crtscts 10.10.10.100:10.10.10.101 115200 /dev/ttyS0 &
In PPP client side :
$/usr/sbin/pppd call ppp-start
where ppp-start file is copied into directory /etc/ppp/peers/ that had the following
-detach /dev/ttyS0 115200 crtscts
noauth
This point to point communication worked fine with RS485 interface. If i had to connect one more node what i need to do. Please clarify with the following
i) Whether the existing pppd takes care of the RS485 with multi node , if so how do i manage giving commands
ii) If there is no direct support how do i go ahead.
I will be grateful if anybody of them could help me with my current problem.
Thanx in advance.
Karthik
