TCP/IP connection between Atari and Linux, using PPP
This little text explains how to establish a PPP 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:
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 !
