Hardware > Serial sync. com port double buffered?

#2991 - ampz - Sat Feb 15, 2003 8:30 pm

From the gbatek document, it sound like the syncronous serial com mode ("normal mode") is single buffered. That's a bit odd... Most serial com interfaces are double buffered to allow back-to-back transmissions without any exotic and/or awkward handshaking.
Can anyone shed some light on this subject?
