Table 10-3: Parity Of The Serial Interface - Siemens Sinumerik 840D sl Function Manual

05.07

COM interface
The COM interface is used for connecting the machine. Interfaces 1 to 256 can
be assigned.
1= COM1
....
16= COM256
Extract from machine configuration file:
[COM]
ComPort =
Note
ComPort=0 is not a valid interface.

Baud rate
The baud rate specifies the transmission rate of the interface.
Baud rates of 110 to 256000 are possible.
Extract from machine configuration file:
BaudRate = 9600

Number of data bits
6, 7 or 8 bits can be evaluated as data bits.
Extract from machine configuration file:
ByteSize = 8

Number of stop bits
1 or 2 bits can be evaluated as stop bits.
Extract from machine configuration file:
StopBits = 1

Parity
The following parities can be defined:

N=No
O=Odd
E=Even
M=Mark
S=Space
Extract from machine configuration file:
