Effect

Stores 1-byte data input from the joystick port 2 in an integer variable.

Notes:

  • This instruction is for general-purpose serial communication at 38400 bps. You can use it when communicating with the terminal software or between two MSX computers.
  • Be careful when writing programs for two-way communication. One computer must be the sender, the other one the receiver. If both computers are in the receiver status, they will deadlock and freeze.
  • If an error occurs during communication or data cannot be received correctly, MSX may freeze while waiting for reception. In such a case, please click the [x] button of "Joy Joy File Server" once. By sending dummy data, the problem may be resolved.
