3.5.3 Configuring the ASCII Interface
The module can be configured so that it starts up either in binary mode or in ASCII mode. Global
parameter 67 is used for this purpose (please see also chapter 5.1).
Bit 0 determines the startup mode: if this bit is set, the module starts up in ASCII mode, else it will start
up in binary mode (default).
Bit 4 and Bit 5 determine how the characters that are entered are echoed back. Normally, both bits are set
to zero. In this case every character that is entered is echoed back when the module is addressed.
Character can also be erased using the backspace character (press the backspace key in a terminal
program).
When bit 4 is set and bit 5 is clear the characters that are entered are not echoed back immediately but
the entire line will be echoed back after the <CR> character has been sent.
When bit 5 is set and bit 4 is clear there will be no echo, only the reply will be sent. This may be useful in
RS485 systems.
