Abstract
A POS terminal includes an application unit that outputs a first command that performs a first operation on a medium to a first communication port, or a second command that performs a second operation different from the first operation to a second communication port; a receiving unit that receives the first command or second command output by the application unit, the first command or the second command being received by the first communication port or the second communication port; a command control unit that converts the first command to a third command, or converts the second command to a fourth command; and a communication unit that transmits the third command or fourth command output from the command control unit to a third communication port.
Claims14
A POS terminal comprising:
- an application unit that outputs a first command that performs a first operation on a medium to a first communication port, or a second command that performs a second operation different from the first operation to a second communication port;
- a receiving unit that receives the first command or second command output by the application unit, the first command or the second command being received by the first communication port or the second communication port;
- a command control unit that converts the first command to a third command, or converts the second command to a fourth command;
- and
- a communication unit that transmits the third command or fourth command output from the command control unit to a third communication port.
A POS terminal control method, comprising steps of:
- an application outputting a first command that performs a first operation on a medium to a first communication port, or a second command that performs a second operation different from the first operation to a second communication port;
- receiving the first command or second command output by the application at a receiving unit before being received at the first communication port or second communication port;
- converting the first command to a third command when the first command is received, or converting the second command to a fourth command when the second command is received;
- and
- transmitting the converted third command or fourth command output to a third communication port.
A non-transitory POS-terminal-readable medium containing a program for controlling a POS terminal, the program comprising:
- instructions for outputting, by an application, a first command that performs a first operation on a recording medium to a first communication port, or a second command that performs a second operation different from the first operation to a second communication port;
- instructions for receiving the first command or second command output by the application at a receiving unit before being received at the first communication port or second communication port;
- instructions for converting the first command to a third command when the first command is received, or converting the second command to a fourth command when the second command is received;
- and
- instructions for transmitting the converted third command or fourth command output to a third communication port.
