I can vouch that polled mode on this IC is rock solid.  As the app note 
states, though, IRQ support cannot be trusted.

I did, though, suggest the rtl IC as a suitable alternative, as it does 
not contain the issue.  I had hoped to bring that IC to the CBM crowd, 
but the standard had already been decided by virtue of SW support before 
I arrived on the scene.

I think the rtl IC has some merit above the 2200/01 IC you noted. It 
requires far less IO space (16-32 versus 141 bytes), though I think it 
still needs a way to hide more of the registers to better co-exist in a 
Coco IO space.

esp8266 registers are the easiest to support (1, if you lock the bps 
rate, 4-8 if you want to put a UART in line.)
