Re: Can a USB driver exposed functions like RS232 COM port?

Alex,

I want to develop a software only solution.

Perhaps they could be persuaded to bundle this as a standalone product.

In any case, you should be able to do this, but you'll need hardware to make
the connection from USB to the serial port connected to whatever is on the
other end of the connection. Who is going to generate, for example, the
handshaking signals? That has to be done via hardware. Once you have your
hardware designed, you can create a USB class driver which makes your cable
or box or whatever it ends up being appear as COMx: to the Windows CE
device. As far as I can think, there are no example drivers for doing this
or any USB-to-serial adapters with Windows CE drivers, though. You might
search the archives of this group using GoogleGroups at groups.google.com
(search microsoft.public.windowsce.*, just in case), and see whether there
are any such devices with CE drivers.

This is a Windows CE group...

Hi,

Yes, the Panasonic tablet PC(hand held device) does not have serial
port
in
it. So I need to use an USB port. I need to develop USB device
driver
which
expose serial COM functions to Citrix ICA client.

Do you have any more insight on such driver?

I was planning to use RDP just for testing purpose.

Regards,

Pranav

Hi,

so you have a hand held device, which will run Citrix ICA client on
it.
This
will allow user of such hand held device to execute a program on
Citrix
Server in a so-called terminal server mode. BTW, Citrix ICA
protocol
is
not
the same as Microsoft RDP one ( even though both serve the same
purpose).

Further, a program which runs in a terminal server mode via Citrix
ICA
protocol on your hand held device needs to use some external
device,
connected to this hand held device via USB port.

Is this correct picture ?

If yes :

If you would have all that but a serial port on hand held device,
you
should
not have any problem accessing your serial port in terminal server
mode.
With usb port instead of serial port, it may become more tricky and
depends
on case.

If not :

more information is needed.

Sincerely
SergeiR

A software application on Host supports only serial port (RS232),
but
my
customer wants this application to use USB port. This is a hand
held
device
and runs in citrix environment, it uses RDP.

Do you know more about this kind of setup? I am still trying
trying
to
understand the whole scenario.

The USB function driver for ActiveSync Client does that.

There's a sample at
C:\WINCE500\PUBLIC\COMMON\OAK\DRIVERS\USBFN\CLASS\SERIAL

But who do you talk with on the Host side? What protocol is
used?

Piet

Hello Guys,

I am writing a USB Device driver for a hand held device.
Application
software running on the device does not support USB, it only
can
make
Serial
COM port function calls. Can any one suggest me, how to write
a
USB
driver
which exposes functions like Serial COM port?
