Table 4.4: Connection Control Options
Option Description
Net-Linked
Links the protocol connection to the status of the network
(Ethernet). Attempts to keep the connection permanently open.
DTR/DSR
Control
Uses the DTR/DSR lines to open and close connections. In tcp-
client mode, the iPocket
232 establishes an IP connection to the
remote host when DSR is asserted and terminates a connection
when DSR is negated.
In tcp-server mode, the iPocket 232 asserts DTR when there is a
valid incoming connection attempt and accepts the connection as
soon as DSR is asserted.
In tcp(tunnel) mode the iPocket 232 both accepts and establishes
connections to the host.
RTS/CTS
Control
Uses the RTS/CTS lines to open and close connections. In tcp-
client or tcp(tunnel) mode, the iPocket
232 establishes an IP
connection to the remote host when CTS is asserted and
terminates a connection when CTS is negated.
In
tcp-server or tcp(tunnel) mode,
the iPocket 232 asserts
RTS when there is a valid incoming connection attempt and
accepts the connection if CTS is currently asserted.
Modem
Enables the iPocket 232 to act as modem to a device connected to
its serial port. The iPocket 232 processes a superset of the standard
Hayes command set, including the ability to answer, dial, and
originate a connection. FTP and HTTP are supported with
extended AT commands.
For implementation notes and a description of supported
commands, see Appendix F: Modem Connection Control.
