hi all…
we developed a usb2ser.sys which shows usb port as a com port for the pC…it is working fine for writing data into the device…and not for reading…if i use only the write function it is working as we intended…when read function is enabled in driver it seems to be the hanging of application after opening the port…
while debugging this problem i came to know that RTS n DTR signals r cleared by the controller and it is not making the device ready for read operation…
in serial driver i saw that using of interrupts manipulation for IOCTLS… i am not doing that thing …is it cause for that problem…? i tried in many ways to resolve this problem
but i am not getting at last it is sending the ioctls for clearing rts n dtr…
can anyone help me to resolve this problem
