Ideal for IT professionals and tech managers needing dependable serial communication solutions. ## Description Convert your existing straight wired cables to null modem or reverser (transmit & receive) cables with these handy, inexpensive adapters. Simply plug these adapters onto the end of a cable and you're done ! Review: These adapters (as sold by dgjiachen) conform to the "Full Handshaking" pinout described on Wikipedia (search for "Null modem"), so by-and-large will work with normal serial ports without any special settings. I have used one to connect a PL2303-based USB serial adapter to the serial port of a server so that I can do some startup troubleshooting via the console. Took advantage of the twin pack, as one shall inevitably go walkies when surrounded by envious techies curious about how I make fixes as close to the metal as possible...
