    Does the reader support PnP at hardware level ?

    This error means that someone has the desired COM
    opened before you decided to do so. So if you want
    to provide services of the reader attached to that COM
    you have to open it so there must be no other client
    who has it opened.

    Subject: VCOMM_OpenComm return IE_OPEN

    Hi! All:

    When I write Smart Card driver(VxD) in 9X

    I meet a problem :calling VCOMM_OpenComm return IE_OPEN.

    Any other method to get the handle of COM port?
    Someone give the suggestion:delay 45 seconds and try again.
    But it doesn't work!

    Any suggestion?

    Thanks a lot!
