I've just added misc/DL.diff to our subversion tree. If you apply this patch to Simh, then you can add these lines to your simh.cfg to make 8 DC-11 devices: set ttix en ; Enable DC/DL-11 device set ttix lines=8 ; We want 8 serial ports set ttix address=17774000 ; Set the address to be a DC-11 set ttix carrier=dc ; Turn on the DC-11 carrier detect bit set ttox 7b ; Set output to be 7-bit, lowercase att ttix 5555 ; Attach serial ports to telnet 5555 I hope we can get the change into the Simh tree.
