[amsat-bb] Fodtrack Serial rotor controller on HamLib

So all this talk about Gpredict got me to look at updating my own setup,
which pre-dated the modern Gpredict capabilites. But being so archaic,
I need some help connecting the dots...
I have Gpredict / Hamlib talking to my Yaesu FT-736R radio for Doppler
tracking just fine, but the rotor is a problem. My controller is
home-brewed, and emulates the subset of the "Yaesu serial protocol" as
output from the original DOS version of FODTrack. The syntax is the
letter "W" followed by the Azimuth, a space, the Elevation, and
terminated with a carriage return (hex 0d). Both the Az and El are
whole decimal integers. When I moved to Linux and Predict (the ncurses
version) in 2002, I modified the software to copy that same syntax, and
all was fine.
Tab forward over a decade to my question: What model "Yaesu controller"
was FODTrack thinking it was talking to? I need to find an equivalent
model for Hamlib's rotctl daemon, and none of the choices seem to
match. They all seem to want to talk to a single rotor (Az or El, not
both). Is there an equivalent model, Yaesu or otherwise, that accepts
"Waaa eee\n" for Az + El positioning?
