3.7.7 Direct Control with TCP/IP
The 9099's WebServer communicates thru port 80. If you write a program to
open a socket to port 80 on the 9099 and send a single line containing the pa-
rameter via the socket, it would be the same as having a browser communicate
with the 9099. You can create a small program to visit, examine or control
the html page variables. Refer to the html pages supplied with your 9099 for
the variables names and to Application Bulletin AB80-17 for more detailed
information on direct control with port 80. An example is:
GET/cgi?%input1%\r\n
'reads F4 temperature
