Special Options (in the Ports form) are space
separated and start with the dash character (-) immediately
followed by the option characters. Use the following special
options for TCP/IP:
A: Allows the TCPIP driver
to be used from Cicode.
-Ia.b.c.d: defines remote
IP address to connect to.
-FC: Allows for a fake
connection. This creates a pretend connection (no actual IP
connection is made). Its intended use is when a driver wants to
support a dummy connection but not talk to a device, or have a
virtual unit. A virtual unit would allow access to driver addresses
which do not need to talk to a device.
-K: sets socket
SO_KEEPALIVE flag.
-LIa.b.c.d: defines local
IP address.
-LPn: defines local
PORT.
-Ma.b.c.d: defines
multicast IP address.
This option can be set using the
[TCPIP]PortName.MulticastAddress parameter. See Debugging a TCP/IP
driver.
-Pn: defines remote PORT
to connect to.
-PXn: defines an extra
port to listen to only in UDP mode.
-RC: Activates the
reconnection retries on reception of FD_CLOSE event. FD_CLOSE is
only received if the Keepalive option is activated. -RC can resolve
issues where the TCP/IP driver is notified of the connection close.
For a more comprehensive handling, the -k option is needed. Retries
can also be activated with the following high-level driver
call:
