Minimal packet configuration: Is it possible?

[Remmie / Rea / Pluisje]

Hi,   Since I only know full linux distributions (SuSE, RedHat), taking up a lot of system resources (HD space, Memory), I was wondering if the following is possible.   I have an old 486sx-25 mhz. Only 4mb of memory. There's an 40 MB harddisk in it, and a 240 MB HD. It also has an ethernet controller.   I would like to run a packet on it, it may be very minimal, but it has to do at least the following:   Packet with a 1200bd baycom type modem (TCM3105) Coppying (rxecho) data from the baycom-port to another PC via a serial link.   Another PC will do the fancy stuff, but i NEED the old 486 to serve as a front end to the radioport.   Any suggestions?   Remco
