Tablet to telescope connection via cable ?

[Astro-Geek]

I'm getting really keen on SkySafari 6,  (in serious danger of defecting from Stellarium 🙂).

As it won't run on my PC I use it on my ten inch Andoid tablet and connect to my skywatcher synscan via wifi.

I'd like to connect via direct cable though, which is a problem with the tablet, as it has no com ports and I have to use an OTG adapter to get the USB port working in host mode.

That does actually work, because I can read USB memory sticks via it.

When I try to use my skywatcher cable though, I have to use a serial to com adapter, and I think it's that link in the chain that is not co-operating.  I know they're a bit fickle with windows anyway, demanding exactly the right drivers.  With it all plugged in, the telescope setup page in SkySafari just shows Wifi and Bluetooth as the options, and no com port appears.

So has anyone managed to connect an Andoid device to a scope by direct cable ?
