You could use the FTDI 5V TTL/UART to USB cable (FT232RQ chip).
Sparkfun sells a version of this cable ($17.95) that has RTS and CTS brought out.
When Sparkfun has "sales" this cable is often discounted further ($11.95).
I use this cable for interfacing computers with the Kenwood 6-pin DIN UART (inverted serial TTL) for remote computer control (CAT) of frequency, etc.
This specific FTDI chipset (FT232L and FT232Q) and its Utility software (FT_PROG) permits INVERTING the serial lines (required for Kenwood usage).
The "other approach" was posted here on amsat-bb back in 2010/2011.
That is a hardware emulation solution by Dave Dowler, KA6BFB (2010) and Chuck Jones, N6BIL for using the Yaesu FT-736R with Ham Radio Deluxe (HRD).
DIY Project write-up.
An OSH-Park PCB board was developed for this solution (above).
