Hi Michael,
Thanks for your help.
Do you confirm that there is no "standard" possibility to change this
baudrate using CT-API protocol only (without proprietary commands),
even the 1.0 update of the standard (which is in German, and I have
not heard of any available translation).
If this is confirmed, I believe that this kind of feature could be
part of MCT the standard. Choosing the COM port is there in MCT, but
the configuration of this COM port is also often required, as 9600
bits/s can be too slow for some applications. And this dynamic
configuration requires some communication between the host and the
reader, which could be part of the standard as well as the API.
Best regards,
Francois

Hello Francois,
if you use a Gemcore-based reader from Gemplus you can send the
"CONFIGURE SIO LINE"-Command to you reader.
This command sets the SIO line parity, Baud rate and number of bits per
character.
The serial port is reconfigured as soon as this command is executed. The
response
is already returned with the newly specified parameters.
You must send two Bytes:
First Bytes 0A(hex)
in the following format:
Bit: 7-5: not used
Bit 4: 0 = no parity 1 = Even parity
Bit 3: 0 = 8 Bits per character 1 = 7 Bits per Character
2 to 0: Sets the baud rate (see table below)
Bits Baud rate
000 RFU (not used)
001 76800
010 38400
011 19200
100 9600
101 4800
110 2400
111 1200
Example:
The two Bytes: 0Ahex 02hex will set the serial line parameter
to 38400 Baud, no parity, 8 bits per character
If you don't use the CT-API-protocol you have to embedded this command in
the TLP224 transport layer:
So, if you send the following (Raw-) Byte Sequence to you reader, the
parameter change will be executed.
(All Bytes in hex)
36 30 30 32 30 41 30 32 36 41 03
(this is as ASCII-character: 6 0 0 2 0 A 0 2 6 A Ctrl-C)
Best regards
Michael
