4.For Retrycounter, enter the number of times the Lantronix unit should try to make a good network connection to a hostlist entry that it has successfully ARPed. The range is 1-15, with the default set to 3.

5.For Retrytimeout, enter the number of seconds the unit should wait before failing an attempted connection. The time is stored as units of milliseconds in the range of 1-65535. The default is 250.

c)Datagram Type

Directed UDP

When selecting this option, the prompt requests the Datagram type. Enter 01 for directed or broadcast UDP.

When the UDP option is in effect, the unit uses UDP datagrams to send and receive data.

d) Modem Mode

In Modem (Emulation) Mode, the unit presents a modem interface to the attached serial device. It accepts AT-style modem commands, and handles the modem signals correctly.

Normally, there is a modem connected to a local PC and a modem connected to a remote machine. A user must dial from the local PC to the remote machine, accumulating phone charges for each connection. Modem Mode allows you to replace modems with WiPorts, and to use an Ethernet connection instead of a phone call. By not having to change communications applications, you avoid potentially expensive phone calls.

To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full verbose), or D7 (echo with 1-character response).

Note: If the unit is in Modem Mode, and the serial port is idle, the unit can still accept network TCP connections to the serial port if Connect Mode is set to C6 (no echo), D6 (echo with full verbose), or D7 (echo with 1-character response).

	Without Echo	In Modem Mode, echo refers to the echo of all of the characters
		entered in command mode; it does not mean to echo data that is
		transferred. Quiet Mode (without echo) refers to the modem not
		sending an answer to the commands received (or displaying what
		was typed).

	Full Verbose	The unit echoes modem commands and responds to a command
		with a message string shown in the table below.

	1-Character	The unit echoes modem commands and responds to a command
	Response	with a single character response.
