Dilwyn, If only 2 machines or nodes are on the Sernet, then a standard null modem leas will do. Try Maplins or any electronics store or I can supply them.
With more than 2 nodes on the serial network, then a special cable or arrangement must be made. As you have suggested, the Sernet is a circular networking system. So that Inputs are connected to Outputs. The actual cable is a little cumbersome, so I thought of making a little hub box for 4 nodes with all the interconnections made. All that is required is straight serial port cables from the network node. I will make a prototype SerHub box it would make the serial networking a lot more easiler than it is now. I am using Sernet v2.22, I am sure there are later versions, but this is version that I have had reliable results on all QL machines. Only failure is Superhermes, which due to the way the SER3 port is coded can not have split speeds under the way SMSQ/E requires Sernet to work. If the SER3 source code were avavilable, I am sure that this problem could be solved.
