c>newmode ? >oldmodes.bat creates a disk file called
’OLDMODES.BAT’ and sends the report in the example above
to it. If the command oldmodes is given:-
c>oldmodes will set COM1 to COM4 as set above.
The exact content of these reports of course will depend on how
your system is set up and how many serial ports are installed.
Using NewMODE Without NewBIOS._________________________________
If neither NewCOM.sys or NewBIOS have not been
installed and NewMode is being run with only DOS then
NewMODE will do its best to meet the requests made of it via
the standard PC ROM BIOS, reporting address and baud rates
for up to the first four COM ports.
Help._____
This still works, reports the reduced functionality available.
Parameter Setting________________
Parameter and address settings work exactly as before, but
only COM1, COM2, COM3 and COM4 are supported. Setting
the IRQ line is of course meaningless, because there is no record
to set and no driver to use the IRQ line.
Query______
This works as normal, with the reduced range COM1 to
COM4. The IRQ settings reported are the defaults industry
standards, IRQ4 for COM1 and IRQ3 for COM2.
