DTECH 15ft COM Port Serial Cable Male to Female RS232 Extension 9 Pin Straight Through Cord

Bottom line: The DTECH 15ft COM Port Serial Cable Male to Female RS232 Extension 9 Pin ($13.98 on Amazon as of 2026-10-06): 15 ft reach places RS232 gear well away from the PC; main trade-off: male-to-female extension only, not a null-modem crossover.
