I am finishing up the board for a user port RS232 interface, and want to add the mods to allow it to be used as a UP9600 interface. I found the mods: Add a wire from M to 5 on user port Add a wire from B,C to 7 on user port Wire L to 6. Before the mods, M was transmit out. BC was receive in, and L was DSR. And DTR (pin E) is not connected at all. DTR doesn;t bother me, as it is output, but the additions of 5 and 7 and the removal of L from DSR input seems like it might cause incompatibilities. RIght now, I have them all on jumper blocks. But, I'm more than happy to remove if people think it is OK. Any ideas? -- Jim Brain, Brain Innovations firstname.lastname@example.org http://www.jbrain.com Dabbling in WWW, Embedded Systems, Old CBM computers, and Good Times!
