[sarex] Computer control of ICOM 1271A?

I'm pretty sure the answer is no, but I'll ask anyway...
Has anyone succeeded in interfacing an ICOM 1271A 23cm transceiver to a computer for Doppler control? In preparation for the ISS L-band uplink, I maybe have barely enough uplink power to get in, but it will need to be right at mid-point on an overhead pass. That's when Doppler shift is the worst.
I have been able to keep up with Doppler on AO-51 L/U by hand (while watching the computer prediction screen), so direct computer control isn't critical, but it seems like a good next step in station automation, if it's possible. The only interface I can imagine is to simulate mike up/down clicks through a parallel port. I am currently running a home-brew client for Predict under Linux, which spits out CAT strings to my Yaesu 736R via a serial port. So, mike-clicks will be a good bit of a re-write.
I guess the only other alternative is some sort of swap of 1271 for a 23cm Yaesu module... Any takers (or is this a bad idea)?
