A communication system enters information into enabled fields of a hypertext based page when a hot-linked identifier is activated by a user. The method further includes, etching the dielectric layer and the protective layer together to form cavities corresponding to sensing surfaces of the chemFETs. The resistivity-sensitive memory elements may be two-terminal resistivity-sensitive memory elements. The second AP instantiates the SSID and the security configuration information and, optionally, the NAT information.
