haukex / kcott - Thanks for the suggestions. As additional explanation, this routine only needs to accept and process input. No response is sent back to the sensor and only one sensor provides input. So the simplest routine possibly is preferred.
kcott - Each message received consists of 5 lines. All messages are identical except for the sensor data in the request line.
   A request line.
   Three header lines (host, connection, user-agent).
   A blank line.
The request line format is:
GET /DATA_String/{300 continuous characters of sensor data}HTTP/1.1
A message is received approximately every minute. Processing by the called routine requires approximately 22-24 msec. Everything seems to work except the listen queue doesn’t seem to clear after the input is read to the buffer resulting in the listen queue overflow.
