2.2.6 Port[x].StopBits
1 or 2
Stop bits signal the end of a character in the data stream. For most applications,
use one stop bit. For slower devices that require more time to re-synchronize,
use two stop bits.
All devices communicating through this port must use the same number of stop
bits.
2.2.7 Port[x].RTSOn
0 to 65535 milliseconds
This parameter sets the number of milliseconds to delay after Ready To Send
(RTS) is asserted before data will be transmitted.
2.2.8 Port[x].RTSOff
0 to 65535 milliseconds
This parameter sets the number of milliseconds to delay after the last byte of
data is sent before the RTS modem signal will be set low.
2.2.9 Port[x].Handshaking
Handshaking is a negotiation process between devices that establishes a data
connection. Select the handshaking type that best matches the needs of the
devices connected to the port.
Value Description
0 No hardware or software handshaking
1 RTS/CTS hardware handshaking
2 DTR/DSR hardware handshaking
3 XON/XOFF software handshaking
2.2.10 Port[x].RTermCnt
0 to 12 characters
This parameter specifies the number of termination characters that define the
end of a received message. Use this parameter if you set the P
ORT [X].T YPE
Port[x].Type (page 54) value to 1, 3, 5, 7, 9, 11, 13 or 15.
2.2.11 Port[x].RTermChar
This array of up to 12 characters specifies the termination characters that define
the end of a received message. Each character occupies one position in the
array. The number of termination characters you enter here must match the
value in the P
ORT [X].RT ERM C NT tag.
