Description
Specifies the number of data bits in each
received character.
Specifies the number of data bits in each
transmitted character.
Specifies the number of stop bits attached
to each transmitted character.
Determines whether the Carrier Detect
signal of the serial port must be set in
order for the IEC station to receive mes-
sages
Delay in milliseconds between activation
of the RTS signal and start of new trans-
mission.
Specifies maximum number of times that
a message is transmitted after timeout.
Maximum waiting time in milliseconds of
a link layer response.
The connection is considered to be alive
if the delay between two consecutive
master messages is shorter than the spe-
cified time in milliseconds.
The type of the data link connection used
on the channel.
