And IIRC the Intel 8251 USART chip has the feature that there's no way to
get it into a known state under certain circumstances (IIRC this happens
if you're initialising it in synchronous mode and don't know how many
bytes you've written to it).

Hi
I think there is a work around for the 8251 but it isn't
all that clean either. You just keep writing commands
until you are guaranteed to do a reset. I'd have to look
at the code I have someplace to do this.
Hopefully, they don't use 8255's to control missile launches.
