Null-Modem Serial Cable, DB25 Male to DB9 Female

This null-modem serial cable connects two DTE devices directly, without a DCE device in between, by crossing the transmit (TXD) and receive (RXD) lines between connectors. It’s commonly used to link two computers or serial devices for direct communication over RS-232.

The cable terminates in a DB9 female connector on one end and a DB25 male connector on the other, wired specifically for null-modem operation rather than a standard straight-through pinout.
