ballamuth's utp-serial wiring

For me to not forget, for you, if you find it useful.

DTE DE-9               DE-9 DTE
1   dcd <- 6        -> dcd 1
  6 dsr <- brown    -> dsr   6
2   rxd <- w-green  -> rxd 2
  7 rts -> green    <- rts   7
3   txd -> w-orange <- txd 3
  8 cts <- orange   -> cts   8
4   dtr -> w-blue   <- dtr 4
  9 ri  <- nc       -> ri    9
 5  gnd == blue     == gnd  5
 5  gnd == w-brown  == gnd  5

Sorted by UTP pairs
DTE DE-9               DE-9 DTE
1   dcd <- 6        -> dcd 1
3   txd -> w-orange <- txd 3
  8 cts <- orange   -> cts   8
2   rxd <- w-green  -> rxd 2
  7 rts -> green    <- rts   7
4   dtr -> w-blue   <- dtr 4
 5  gnd == blue     == gnd  5
 5  gnd == w-brown  == gnd  5
  6 dsr <- brown    -> dsr   6
  9 ri  <- nc       -> ri    9
  
UTP crossover makes the twist:
RJ-45                    RJ-45
1 txd w-orange  w-green  rxd 1
2 cts   orange    green  rts 2
3 rxd w-green   w-orange txd 3
4 gnd   blue    w-brown  gnd 4
5 dtr w-blue      brown  dsr 5
6 rts   green     orange cts 6
7 gnd w-brown     blue   gnd 7
8 dsr   brown   w-blue   dtr 8

I know about Yost standard, but it is inconvenient for me, and this wiring is very easy to use with DE-9 connector and T568B cable (colors should be changed appropriately using T568A cable).
