I believe that uart works for the 16550 part, but haven't tried it
The uart probably works for some 16550 based devices but does not work
for other one like multi-port devices.
The design principle of uart(4) is that it does not know
about multi-port hardware. It controls a single serial
port only. For multi-port hardware you must have multiple
nodes on a bus or use an umbrella driver, such as puc(4),
quicc(4) or scc(4). Those drivers provide attachments for
I suspect that support for multi-port devices is not to
hard to do on pc98...
