Hey serial-knowing friends: are all RS232 DB25 pinouts the same? Are any two DB9-to-DB25 adapters going to be identical? I have a DB25-equipped serial device I’m getting a USB interface for, but looks like most USB interfaces only come in DB9 flavour.

@misty I don't remember any unusual DB25 serial pinouts, and all the 9/25 adapters I have seen were the same (though it's not impossible there's some that are wired for null modem).
