The Le field for that last CT_data call is set to 255.
Ok, it is set to zero for the call to retrieve the ATR. But
doesn't this mean to retrieve all data that is available?
(if I dump the received data to stdout the correct ATR is
shown)

Daniel,
I do not know what CT_data does, but shouldn't you be setting LE ? since
it's an IN_OUT APDU ?

Hi,
I'm using towitoko-2.0.7 ctapi to execute commands on a BasicCard
(4.5D Rev C, basiccard.com) using T1.
On the BasicCard I have the following command with CLA=0x80 and
INS=0xaa which simply creates a file and fills it with 1's. After
that the length of the file and the input data is returned.
Command &H80 &HAA TestCmd( data$ )
Private One As Byte = 1
Private I As Long = 0
Open "123" For Binary As #1
For I = 1 To 300
Put #1, , One
Next I
data$ = Str$( Len( #1 ) ) + ":" + data$
Close #1
End Command
To execute the command on the card I do the following CT_data calls:
unsigned char dad;
unsigned char sad;
unsigned short lenc;
unsigned char cmd[ 255 ];
unsigned short lenr;
unsigned char rec[ 255 ];
CT_init( 1, PORT_COM1 )
/* reset CT */
dad = CT;
sad = HOST;
lenc = 4;
lenr = 255;
cmd[ 0 ] = 0x20; /* CLA */
cmd[ 1 ] = 0x11; /* INS */
cmd[ 2 ] = 0; /* P1 */
cmd[ 3 ] = 0; /* P2 */
if( CT_data( 1, &dad, &sad, lenc, cmd, &lenr, rec ) != OK ) {
fprintf( stderr, "communication error\n" );
exit( 1 );
}
/* reset ICC return ATR */
dad = CT;
sad = HOST;
lenc = 6;
lenr = 255;
cmd[ 0 ] = 0x20;
cmd[ 1 ] = 0x11;
cmd[ 2 ] = 1;
cmd[ 3 ] = 1; /* P2 return ATR */
cmd[ 4 ] = 0;
cmd[ 5 ] = 0;
if( CT_data( 1, &dad, &sad, lenc, cmd, &lenr, rec ) != OK ) {
fprintf( stderr, "communication error\n" );
exit( 1 );
}
/* call command */
dad = 0;
sad = HOST;
lenc = 9;
lenr = 255;
cmd[ 0 ] = 0x80;
cmd[ 1 ] = 0xaa;
cmd[ 2 ] = 0; /* P1 */
cmd[ 3 ] = 0; /* P2 */
cmd[ 4 ] = 3; /* Lc */
memcpy( &cmd[ 5 ], "ABC", 3 ); /* send some data */
cmd[ 8 ] = 255; /* Le */
if( CT_data( 1, &dad, &sad, lenc, cmd, &lenr, rec ) != OK ) {
fprintf( stderr, "communication error\n" );
exit( 1 );
}
The last call of CT_data fails with the error code ERR_TRANS.
When removing the for loop on the BasicCard everything works
fine. Maybe because the command returns in less time?
Can anybody help?
Thanks a lot,
Daniel
