To enable the hostlist:

1. Enter a Connect Mode of 0x20 (2X), where X is any digit. The menu shows you

a list of current entries already defined in the product.

2. To delete, modify, or add an entry, select Yes. If you enter an IP address of

0.0.0.0, that entry and all others after it are deleted.

3. After completing the hostlist, repeat the previous step if necessary to edit the

hostlist again.

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.

Datagram Type

Directed UDP

When selecting this option, you are prompted for the Datagram type.

Enter 01 for directed or broadcast UDP.

When the UDP option is in effect, the unit never attempts to initiate a

TCP connection because it uses UDP datagrams to send and receive

data.

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 XPorts, 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).
