  • L-frames are link control frames used by the data link layer for managing the communications link between the PC and TERMINAL. At present there is a single L-frame command defined:
  • N-frames are negative acknowledgment frames or NAK frames, signalling a negative acknowledgment of a received frame.
  • the TERMINAL sends this frame after receiving an invalid frame (incomplete or bad checksum) from the PC.
  • the LEN for such frames is 0.
  • E-frames are frames containing event messages from the TERMINAL.
  • the I-block consists of a type byte and any relevant data.
  • M-frames are event frames and are sent by the TERMINAL when it detects a change in the state of its buttons or when sufficient X-Y movement has occurred. M-frames are the only frames not to conform to the frame structure above. Each M-frame is a fixed 4 bytes in length, and has the following format:
  • This command queries the TERMINAL for device. This enables the PC to query for such parameters as the TERMINAL serial number and default ICC clock rate.
  • Command Format :
  • This command queries the TERMINAL for the ICC. This enables the PC to query for such parameters as card presence and the last ATR string.
  • Command Format :
  • This command queries the TERMINAL for current protocol This enables the PC to query for such parameters as the current IFSC and IFSD.
  • Command Format :
  • This command is used to set protocol parameters used in the TERMINAL'S interaction with the smartcard. This enables the PC to change such parameters as the current IFSD. Command Format:
  • This command may be used to set the mode of the integrated smartcard terminal device.
  • the integrated smartcard terminal device may operate in either standard mode, or full-integrated smartcard terminal device mode. This command may also set a new communications baud rate.
  • Command Format :
  • This command may be used to set the integrated smartcard terminal device to operate on a specific smartcard type. By default, an asynchronous card type is selected.
  • Command Format :
  • All commands received by the TERMINAL are either port specific or non-port specific.
  • This command enables one of the smartcard ports on the TERMINAL. For all commands received after this command that are port specific, the TERMINAL will interact with the smartcard in the port specified by this command. On reset, smartcard port 0 is enabled.

  • Table 5 shows an example of a method by which the personal computer arbitrates messages between smartcard terminal commands and X-Y position information commands. If the command is less than a certain value, then the command is a smartcard terminal command. If the command is greater than or equal to a certain value, then the command is an X-Y position information command.

Abstract

L'invention concerne un terminal à carte intelligente se présentant sous la forme d'un dispositif pouvant lire des informations à partir d'une carte intelligente et écrire des informations dans une carte intelligente. Ce terminal comprend un lecteur de carte intelligente et un organe de réunion et de transmission de données qui sert à recevoir des données de position provenant d'un pointeur pour écran d'ordinateur à communicabilité sérielle, et provenant du lecteur de carte intelligente. L'organe de réunion et de transmission de données permet de transmettre des informations de position à partir du pointeur, et des informations de carte intelligente à partir du lecteur de carte intelligente vers un ordinateur associé, et de recevoir des informations à écrire dans la carte intelligente à partir de l'ordinateur. L'organe de réunion et de transmission de données réunit des informations de position et des informations de carte intelligente dans des trames séparées avant leur transmission en série, puis il marque chaque trame selon qu'elle contient ou non des informations de position et des informations de carte intelligente. Un tel terminal à carte intelligente s'utilise, de façon caractéristique, sous forme de périphérique pour un ordinateur, par exemple un ordinateur personnel, un poste de travail, un serveur de réseau ou un ordinateur de réseau.
