.Sh NAME

.Nm cmx
|
|
.Nd Omnikey CardMan 4040 smartcard reader device driver
|
|
.Sh SYNOPSIS
|
|
.Cd device cmx
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the PCCARD based
|
|
.Em Omnikey CardMan 4040
|
|
smartcard reader.
|
|
The driver provides a character device special file based
|
|
.Em Chip/Smart Card Interface Devices (CCID)
|
|
interface. The driver implements what the vendor calls the
|
|
.Em Synchronous API
|
|
onto the smartcard reader device.
|
|
.Pp
|
|
Reading and writing is synchronous, meaning that a call to
|
|
.Xr write 2
|
|
directly corresponds to a complete CCID command sent to the
|
|
device, while the following
|
|
.Xr read 2
|
|
will return the complete answer from the reader. There is no
|
|
support for partial reads or writes. There is no upper limit on
|
|
CCID request or response sizes, but the complete CCID request
|
|
must be sent to the driver in
|
|
.Xr write 2
|
|
and the complete CCID response must fit into the buffer
|
|
supplied to
|
|
.Xr read 2 .
|
|
.Pp
|
|
Non-blocking I/O,
|
|
.Xr select 2
|
|
and
|
|
.Xr poll 2
|
|
are supported and work as expected. An open file descriptor
|
|
will always be ready for writing, but only ready for reading
|
|
if the device indicates that it has data available.

|
|
Userland smartcard code written for the vendor's Linux drivers

should work with the

|
driver without modification.

The
|
|
.Nm
|
|
driver was written by
|
|
.An Daniel Roethlisberger Aq Mt daniel@roe.ch ,
|
|
originally based on the Linux driver v1.1.0 by
|
|
.An Omnikey GmbH Lk www.omnikey.com .
|
|
Early testing and bug fixes by
|
|
.An Marcin Cieslak Aq Mt saper@system.pl .
|
|
.Sh BUGS
|
|
.An -nosplit
|
|
The way the
|
|
.Nm
|
|
driver talks to the CardMan 4040 is a bit rough. Due to the
|
|
complete lack of hardware documentation other than vendor drivers
|
|
for other operating systems, the gory details of the device's
|
|
I/O registers are not understood very well. There may be error
|
|
conditions which can only be solved by physically reinserting the
|
|
reader.
