Those options are still there, you need to use icanon as an option to stty to use them.

xcase, iuclc, olcuc, probably more options I am forgetting.

Actually, I think that was the Windows FTDI driver doing the sabotaging.
They too were burned by the chip ripoffs so made an attempt to "get even".
If the Windows FTDI driver detected a non-FTDI chip, it would refuse to
enumerate it and that port was not useable from Windows.

However the open-source FTDI driver, which most people use in their Linux
kernel, did not do this evil bad thing.  Therefore, your counterfeit
yet functional FTDI-like port will still work in Linux.

This is extremely common in these programming cables for various ham
radios--  the TYT and clones in particular.

Yup and it will with Linux too.

So, how are you guys getting your Linux with 110 baud interfaces to
handle uppercase only TTYs?

I played with this a couple years ago and failed because it seemed like
all the IOCTLs in the kernel, and "stty" and "getty" options relating
to uppercase had been deprecated.  I could not get there with a modern
distribution.  Have they put those goodies back?
