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...] -- David Herron, cbosgd!ukma!david, david@UKMA.BITNET, david@ms.uky.csnet (I'm also "postmaster" at all those addresses) (And "news" and "netnews" and "uucp" and ....)

YES, THE COCO3 HAS THE SAME OLD SERIAL PORT, BUT THE NEW HIGH SPEED MODE WILL ALLOW MORE RELIABLE TRANSMISSION AT HIGHER BAUD RATES.

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). -- Roger Sanderson Electrical Engineering Dept. University of Waterloo Waterloo Ontario Canada N2L 5E6 {decvax,allegra,ihnp4}!watmath!watdcsu!rsanders

THE COCO III STILL HAS THE SAME "BITBANGER" RS-232 PORT. BUT, WITH THE NEW HIGH SPEED MODE, HIGHER BAUD RATES CAN BE USED MORE RELIABLY. ------- VICTOR RICKER
