Just be aware that most of these RS-232 to whatever converters don't
deal with the full set of signals in RS-232, just the TXD, RXD and GND
signals.
Therefore hardware flow control (RTS/CTS) won't work. If you have a
vintage device, it might need hardware flow control or other signals
in RS-232 for it to function properly and these devices won't handle
that.
