I want to connect XT with 486 could this be a problem ?? I dunno but this is the way I think it is supposed to be for a proper null modem cable with out disabling your rts and cts and all them goodies :) 2 goes to the other 3 3 goes to the other 2 4 goes to the other 5 5 goes to the other 4 7 goes to the other 7 8 goes to the other 20 20 goes to the other 7 This one should work but it is not guarranted to work for a sure thing but you lose the auto hang up and things you can try.... 2 goes to the other 3 3 goes to the other 2 4 jumpered to 5 on both sides (as in on the same end of the cable) 6 jumpered to 8 jumpered to 20 also on both sides 7 goes to the other 7 and well if these dont work give up like I do and call someone *grin* -- ziggy@r-node.pci.on.ca <--- New and impoved fastest route :) USE IT!! ziggy@r-node.gts.org | Have you rubbed noses with an Eskimo today?? ziggy@zooid.guild.org | My inability to spell and gramatize are no adrian@skypod.guild.org | reflection on the GENERAL CANADIAN intelligence!!
