15 Foot DB9 Male to Female RS232 Extension Serial Cable - 28 AWG Shielded

Bottom line: The 15 Foot DB9 Male to Female RS232 Extension Serial Cable ($9.63 on Amazon as of 2026-10-06): Straight-through pin wiring extends existing RS-232 links, no remapping; main trade-off: male-to-female extension only, not a null-modem or crossover cable.
