Question:

	Does anybody know if the CoCo-III still has that stoopid
	old bit-banged serial port?  I haven't seen anything yea
	or nay in Rainbow or here.

[Doesn't change my decision about buying one... I've already got
 my deposit down... I just wanna know ya see...]

It is my understanding that , yes they still use the bit banger, however
there is a facility for generating timer interupts. These can be used
so many times per bit to give some interuptability.
See the article in Nov. Rainbow about TERM3.
He samples 5 times per bit (I think).
