Ctrl Command rs232_write_text
Function sends a text string (character-by-character) to the RS232 interface.
Call
rs232_write_text( pData )
Parameter pData PC memory address of the first character (byte) of the to-be-sent text string as
a pointer to a null-terminated string.
Comments • This command is split into an appropriate number of rs232_write_data commands.
• During execution of this command no further control commands can execute, but the
board’s list execution is not affected. If an executing list itself contains
rs232_write_text_list commands, rs232_write_text should preferably not be used so
as to avoid conflicts (race conditions).
• Also see chapter 9.1.6 "RS232 Interface", page 207.
