I do believe the shortest patch cord length for 10/100Base-T is 1 meter.

We all hear about max cable lengths for Ethernet.  But is there a
minimum?
If the TX pair of one side connects to the RX pair of the other, then
collisions, if any, happen at the ingress of the hub or switch in the
buffer, or on the buffer of the nic if just using a really short cross
over,
is this right?  I've looked and looked, and haven't been able to get an
answer that says "the minimun length of a Category 5 100Base connection
is x
feet"  even the spec seems to be silent on it.  What am I missing in my
knowledge of physics and electronics?

p.s.  My foot long patches between hosts and a hub don't seem to cause
errors.  I'll stick a sniffer in this week and see if I see any.  I'm
manufacturing these 3 inch patch cables for my test.
