ewan.paton · Posted: Sat Mar 27, 2004 3:43 am Post subject: networking via a serial cable?

im sure i have seen this done but i am not even sure what cables i need. basicly i have a donkeys old toshiba satellite pro 400 laptop{1} which has lost the network dongle{2} and only has a floppy disk drive which i want to put a linux on.
i seem to remeber it being posible to connect 2 pcs together with a serial cable to network them together, any ideas how thanks

{1}only 40 meg ram but a 120mhz processor should be ok as an xterm
{2} anyone knows somewhere replacments can be had will be a godsend

I don't know in linux, but back in the early days of dos there was an application called Laplink wich did exactly this. Perhaps you can use it as a last resource under dosemu.

Hello,

I have an olp laptop whithout CD-rom drive and I have use a serial cable null-modem with the SLIP protocol.

NB : first enable support for SLIP in your kernel

You probably want to use slip. If that doesn't have what you need, look at ppp.

Oh, by the way. An ethernet connection is really two serial ports, one for each direction. Only four conductors in use for full duplex. There's a lot of extra stuff behind it, but it was all developed off of the serial port model.
