What could be the problem? > The above pinout appears to be a useless mix between an 1:1 and a null-modem adapter. For the null-modem adapter you need pin 2 of the D-Sub 9 conntected should be connected to pin 2 if the D-Sub 25 one, and pin 3 to pin 3, while the other connecteions in the above pinout actually is close to a null-modem adapter. For a complete D-Sub 9 to 25 null-modem pinout see here: http://pinouts.ru/SerialPortsCables/Nullmodem9to9_pinout.shtml Marius
