Hi

THanks for the responses. I actually decided to swap this round and look for positive responses in the ranges 200-400 instead of 500 for a negative response. I managed to get this working using the following:

Send string:

HEAD / HTTP/1.0\r\n\r\n

Receive string:

HTTP/1.[01] ([234]0[0-9])

Thanks
