Re: How to support a lot of serial port in WCE42?

I take that back. You do have to modify and recompile the driver to remove
the prefix in order use DEVFLAGS_NAKEDENTRIES. Otherwise there would be no
way for device to determine which function does what. It also looks to be
supported in 4.2...

That probably does work. I was thinking you would have to at least
recompile the driver in order to remove the prefix if you used that flag,
but I guess you could leave it as is. No reason I know of the naked
function name can't be COM_xxx. I'm not sure about its availability in
4.2 either...

There is a flag you can put in registry to remove prefix requirement in
the source code to allow this... However, Dean, you might be right,
because I'm not sure this flag is already supported in CE 4.2

Offhand, I don't think that will work. The prefix needs to match the
stream driver entry point, so a change from COM to XYX requires a
recompile of source code.

you can use the same driver (let's say serial.dll) and just change the
prefix without having to create a new driver

Unfortunately, my platform is base on WCE42, it seems that WCE42 is
not
support driver index large than 9, so, should I create another driver
and use
different prefix name to support each ten com port? Is there any other
smart
way to support this in WCE42?

After Windows CE 5.0 thiere is no limitation on driver's index.
If you have com port more ten, the index will go over ten. If index
is hight
than 10, you only can use (open) device by $device name.
Like
CreateFile(TEXT("$device\com12")...);

Hi, all

I own a device with 12 serial ports, I've write a driver and
success to
load
9 instances to support from COM1: to COM9; But when I try to load
instances
to support COM10/11/12, it failed. I can't find activated
information in
HKLM\\Drivers\\Active.
What's the way to support serial ports up to 10 and more? Any
suggestion
is
very appreciated!

Daric
