Daniel Dallmann's UP9600 interface

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 

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?
