I recently posted a query regarding multiple serial ports and ..

But Everything that Commodore has said is that 2.0 will solve the
multiple-port problem. Every reply so far leads me to believe that we
are no better off than the solution for 1.3 (which is what you just
restated.) Besides, I can't see why Bryce would be so emphatic in the
AmigaMail article and then C= just lets it drop. As I understood it
the following mechanism was to be in effect.
DOS serial.device Hardware port
ser: Unit #
ser1: 0 Default port, redirectable to any other real port.
ser2: 1 Builtin serial port on Amiga
ser3: 2 First port on first AutoConfig'd serial card
ser4: 3 Second port " " "
... ... .....
serx: n First port on next AutoConfig'd serial card
serx+1: n+1 Second port " " "
What wasn't stated was how the actual code to handle the various
ports got control from the new serial.device or how DOS was to get at
anything that didn't belong to serial.device. There is a new
serial.device under 2.0 but maybe that was nothing more than a
maintainence release. Other E-mail replies has stated that C= has a
complete replacement serial.device with their 8 port card :-(
Could someone from Commodore enlighten me?
