For some scenario data in the port is lost for WinCE(Read 6927 times)
I just have small question about Eltima virtual serial port driver for WinCE.

For some scenario data in the port is lost.

For example: some application create virtual port and writes some data to the port, another application reads this data from the port by system function “ReadFile”, so in that case for long time testing ( for example file with size ~ 5-10 Mb) some time data is lost. Function DeviceIoControl with flag IOCTL_SERIAL_VSPD_Write return correct written size.

It can be 5 bytes maybe more. But what strange some time everything is ok.

If we will use another scenario like: one application create virtual port and just read data another application open it like system port and write data by function “WriteFile” all time data received complete.

Nave you meet something similar?

Look forward your answer.

Paul Muraviev.
