Re: selcting right serial driver

You are corrent. All the serial port drivers have the same std entry
points to install the driver and create devices.

I don't think you want to add "another" serial port device - you just
want to use/hack ns16550serial.c. Keep the same entry points in your
driver as the standard ones, and usrRoot willl call your tyCoDrv entry
points.

Include your file in the project and you should be good or put in in
your make file directly.

Hi all,
If I am correct in ursroot() serial port driver is initilized
by calling
tyCoDrv() and as many serial ports are there that many serial devices
are
created by tyCoDevCreate(...)
But in the folder \Tornado\target\src\drv\serial\ there are many files

each coresponding one serial device ... in which tyCoDrv() is defined
in all the files
coresponding to the device , while linking how come linker comes to
know about which
serial port i am using( i am using 16550 uart).

If I want to write my own driver for serial port what are the things i
have to
do before calling mytyCoDrv() because already a driver for serial port
will be instled in
usrroot() and a device is created linking that driver.
