StarTech.com 6ft Straight Through Serial Cable - DB9 M/F (MXT100) Gray - M/F

Bottom line: The StarTech.com 6ft Straight Through Serial Cable: Straight-through DB9 M/F wiring extends serial mouse or EGA monitor runs by a full 6ft; main trade-off: straight-through pinout only, so it will not work as a null-modem crossover cable.

Cons

  • ✗ 6ft is the single length offered here with no shorter or longer option
