Re: TP755Cs/LINUX Slackware 2.2.0 Installation

Someone asked about the "null modem" twisted pair cable for a direct (say)
ThinkPad-UnixBox connection.  I misplaced the sender's address so I'll
post here.  This is from the FAQ on ethernet.


03.11Q: Can  I  connect  the  10BaseT  interface  of  two devices  directly
        together, without using a hub?
     A: Yes, but  not more  than  2 devices, and you  also  need  a special
        jumper cable between the two 10BaseT ports:

          RJ45 pin                   RJ45 pin
          ========                   ========
             1 <--[TX+]--------[RX+]--> 3
             2 <--[TX-]--------[RX-]--> 6
             3 <--[RX+]--------[TX+]--> 1
             6 <--[RX-]--------[TX-]--> 2


One of our technicians put it together for me it about three minutes
and it works very well.

Another thing, if you are connecting to a Sun, be sure to not disable
the link-test (on the Sun).  Yes, it's a silly thing to do, but I did
it a long time ago because I didn't want to keep seeing some even sillier
start-up messages at boot time.  And I never dreamt I'd want an ethernet
at on my "standalone" workstation.

Cheers,
