The EtherPaths and the LAN are completely transparent to PC
application and serial port device.
Server Mode
This mode requires only a single EtherPath. The EtherPath is
connected to the serial port device, and to the LAN.
Users on the LAN can then connect to the serial port device and
communicate with it via Telnet, using any assigned IP and port
address. Most LAN connected workstations provide support for
communication via Telnet.
A special-purpose utility program or port redirector program may be
used instead of Telnet, or the user may create custom software using
Visual Basic, C++, or other network programming tools. By using
port redirection, the EtherPath may function as a remote serial port
on a PC.
Point-to-Multiple-Point (
EtherModem
) Mode
Point-to-multiple-point (
EtherModem
) operation allows a single
EtherPath running in client mode to connect to multiple server-
mode EtherPaths, one at a time, under the control of the attached
RS-232 device. The client operates similar to a modem with “AT”
dialing enabled. The attached device treats the EtherPath as if it
was a modem, using remote IP addresses instead of telephone
numbers.
Reverse Telnet (Telnet Client) Mode
This mode requires only a single EtherPath. The EtherPath is
connected to the serial port device, and to the LAN.
The EtherPath will connect to most remote telnet servers under user
control by using “reverse telnet” or telnet client operation. The
