[comp.sys.apple2] Serial I/O and accelerators

JDB8042@RIGEL.TAMU.EDU (John D. Baker ->An Apple ZCPR3 nut//) (02/19/91)

A recent message I read here (I forget which) leads me to believe that
an accelerator chip (like 4MHz, 8MHz ZipChip) would alleviate the problem
of dropped characters in serial I/O.

Is this, in fact, the case?  Please explain.  If not, please explain.
This is from the standpoint of any non-GS Apple ][.

I would assume that the more rapidly the CPU is able to grab bytes and put
them where they are supposed to go, the less likely your routine is to miss
characters.  Of course, watch out for those memory refreshes.

Thanks.

PS. This is also from the standpoint of reading|writing directly from|to
the device I/O ports in the $C0xn area (where x=$80 + slot#*$10 and n runs
from $0 to $F).
