  When performing a command, the received command or replay data is sent 

back. 

 

  When the received command can not be performed such as the "busy" state, the 

code " 

I " is sent back. In this case, insert a delay time. Electrical noise may be 

the cause of this error. 

 

  When receiving an undefined command (unknown command), a "?" is sent back. 

 

  When there is insufficient memory to store the data of the UFC commands, an 

“M” is sent back. 

 

  Optional addresses can be appended to a command. The address form is 

"@address" and the address is specified at F-Function F06. The reply (data or 

error code) is also sent with the address. 

Example: The command is "Display net data". The address is 23.
