&gt;Hi everyone,
&gt;
&gt;I'm trying to make a management cable for my Cisco uBR904 cable modem, since it
&gt;didn't come with one when I bought it, and I'm wondering if anyone can help me
&gt;with the pin-outs. Like other Cisco management cables, it's a serial cable with
&gt;RJ-45 on the modem end, and serial (DE-9) on the computer end.
&gt;
&gt;In general I know you need to cross the TX and REC pins for serial
&gt;connections, but do you need to do the same for DTR and DSR? Or does DSR on the
&gt;cable modem connect to DSR on the computer's serial port, and DTR go to DTR?
&gt;Should my pinouts go like this:
&gt;
&gt;  modem     computer
&gt;  TX   ---&gt; REC
&gt;  REC  ---&gt; TX
&gt;  DTR  ---&gt; DTR
&gt;  DSR  ---&gt; DSR
&gt;
&gt;or like this:
&gt;
&gt;  modem      computer
&gt;  TX   ---&gt;  REC
&gt;  REC  ---&gt;  TX
&gt;  DTR  ---&gt;  DSR
&gt;  DSR  ---&gt;  DTR
&gt;
&gt;(note that I'm not necessarily indicating signal direction in the above, just
&gt;connections)
&gt;
&gt;Thanks.
