7: Setup Mode: Channel Configuration
WiBox® 2100E Device Server User Guide 56
4. For Retrycounter, enter the number of times the WiBox 2100E device server 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 10-65535.
The default setting is 250.
d) Datagram Type
Directed UDP
When selecting this option, you are prompted for the Datagram type.
Enter 01 for directed or broadcast UDP. Datagrams of type 01 can be
sent as a broadcast by enabling the Send as Broadcast option. The
default is not to broadcast.
Note: Datagrams are sent as subnet-directed broadcasts.
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.
e) 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 the WiBox 2100E, 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), D7
(echo with numeric response), CF (modem responses only, numeric response), or CE (modem
responses only, full verbose).
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), D7 (echo with numeric response, CF (modem responses only,
numeric response), or CE (modem responses only, full verbose).
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).
