TCP/IP connection between Atari and Linux

PPP - Point to Point Protocol

This little text explains how to establish a SLIP connection between two Atari, or between an Atari and a PC under Linux, connected with a Null-Modem cable. The Atari uses Mint and MintNet.
Note: if you use MiNT 1.15.12 or older, install HSModem to have high speed serial ports.

Step 1: Give an IP adress to each machine

I give these IP adresses to my machines:
192.168.0.1 : Linux machine (name:pclinux)
192.168.0.2 : Atari machine (name:atarimint)

Edit /etc/hosts on both machines, to add the lines:

-- /etc/hosts
192.168.0.1	pclinux
192.168.0.2	atarimint
--

Step 2: Start the connection on the PC

Replace /dev/ttyS0 by the serial port you connected the Null-Modem cable.

pclinux# pppd -detach crtscts lock noauth local 192.168.0.1:192.168.0.2 /dev/ttyS0 115200 &

to affect a PPP interface, running at 115200 bauds to the serial port.

Step 3: Start the connection on the Atari

Replace /dev/ttyS1 by the serial port you connected the Null-Modem cable.

atarimint# pppd -detach crtscts lock noauth local 192.168.0.2:192.168.0.1 /dev/ttyS1 115200 &

Do the same thing as on the PC.

Step 4: Test the connection

Begin with a ping on both machines.

pclinux# ping atarimint

on the PC

atarimint# ping pclinux

on the Atari

If packets are transmitted, it works ! (You're the king of the world !!!)
