SCREENSHOT 5. We are now
connected to the SPECTRUM ACE
2a via a TCP socket.
SCREENSHOT 4. The VT100 is one of the greatest terminals
of all time. Everybody that is anybody in the terminal emulator
business emulates this terminal or one of its many variants.
rate is the result of taking the default values in the WLAN
data rate configuration.
The 802.11 up indicator is supported by the i WEM-
1001’s DHCP-assigned IP address of 192.168.0.112. The
At this point, there are no external applications
calling themselves host. The i WEM-1001 only knows
about one host, which happens to be the router.
The local and remote ports are at their default
values and the i WEM-1001 is running its built-in TCP
server application. As soon as I enter “exit,” DATA
will replace CMD and the i WEM-1001 will become a
serial to ethernet bridge.
SCREENSHOT 6. I used the
Hyper Terminal Send Text File function
to load this little program over the
TCP socket connection.
SCREENSHOT 7. ALEC and the
SPECTRUM ACE 2a are like peanut
butter and jelly.
The point behind this discussion is to allow the
SPECTRUM ACE 2a console port to be accessed
from anywhere. The i WEM-1001 hookup is simple
and easy. As you can see in Photo 4, the i WEM-The ACE 2a works best with a 19200
Hyper Terminal VT100 session. So, let’s configure a
Hyper Terminal WINSOCK emulator session
beginning with Screenshot 2. Instead of the
normal serial interface, we’re going to configure
Hyper Terminal to use an Ethernet interface.
We know that the i WEM-1001 was leased an
IP address of 192.168.0.112 by the router on the
EDTP network. We also know that the i WEM-
1001’s local port is 1000. The combination of its IP
address and local port form a TCP socket. A TCP
socket is not more than a communication
endpoint. In this case, our TCP socket is a server
socket that listens on port 1000 for incoming
