Abstract:
|
|
|
|
This module contains the functions for the 220 serial smart card reader.
|
|
Most functions herein will be called by the smart card lib.
|
|
|
|
|
|
Environment:
|
|
|
|
Kernel mode only.

Revision History:
|
|
|
|
- Created December 1996 by Klaus Schutz
|
|
|
|
- Modified December 1997 by Brian Manahan for use with
|
|
the 220 reader.

Routine Description:
|
|
|
|
The smart card lib requires to have this function. It is called
|
|
to set up event tracking for card insertion and removal events.
|
|
We set the cancel routine so the IRP can be canceled.
|
|
We always return STATUS_PENDING and the Lit220NotifyCardChange
|
|
will signal the completion when called from the Lit220InputFilter.

Arguments:
|

SmartcardExtension - pointer to the smart card data struct.

Routine Description:
|
|
|
|
This routine sends a command to the reader.
|
|
SerialIo is used to write the command to the reader synchronously.
|
|
We then wait for an ACK from the reader (by waiting for a signal from
|
|
the Lit220InputFilter) so we know it received the command OK.
|
|
If data is expected we wait for the data event signal from the
|
|
Lit220InputFilter to indicate that the data is ready.

Routine Description:
|
|
|
|
This function sends an SCARD_COLD_RESET, SCARD_WARM_RESET or SCARD_POWER_DOWN
|
|
to the reader. For cold or warm reset we set a flag indicating that an ATR
|
|
is expected. Once the Lit220InputFilter receives the ATR it will update the
|
|
card capabilites.
