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

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.

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?

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?
