The maximum baud rate of the Com-Server 3x Isolated is
115,2kBd, which corresponds to a divisor of 1. 230,4kBd is
only available as standard baudrate.
The currently configured baud rate is displayed when selec-
ting the submenu SETUP Port x (serial) r UART Setup.
9�1�2 The handshake modes
(SETUP Port x r UART Setup r Handshake)
This menu provides three standard modes for flow control of
the serial port. As opposed to these predefined handshake
profiles, you can use the Special submenu to specify the func-
tion of each control signal individually. Details on the control
line functions are contained in the description of the submenu
Handshakle r Special.
n
Hardware handshake
Flow control is handled using the RTS and CTS signals.
The Com-Server only sends data to the serial device if
the CTS input is High. In the opposite direction the Com-
Server indicates readiness using the RTS line.
Function control signal: RTS: Flow Control
DTR: Show Connection
CTS: Flow Control
DSR: NO
n Software handshake
The software handshake is implemented using the two
ASCII characters (11H)=XON and (13H)=XOFF. In the stan-
dard setting Software Handshake these two codes are con-
sidered by the Com-Server as control characters and are
