[ct-user] NETWORK 3 PC's vs 1 PC

[Ed Parish K1EP]

There are two ways to connect four computers using serial ports.  The first method requires that two of the computers have two serial ports.  

PC1/sp1------PC2/sp1 PC2/sp2------PC3/sp1 PC3/sp2---------PC4/sp1

The other method only requires one serial port per computer, however, you must make up special cables.  It is called LOOP mode.  Basically, you connect pin 2 of one computer to pin 3 of the next computer in a loop.  For the degenerative case of only two computers, the cable is essentially a cross over or null modem cable.  Otherwise, you will have to construct special cables.  You can not connect cables as you described below.
