Send 0x69 then 0x2077 then 0x0a from buffer, one byte string at a time

   echo i w|a.out -v 8001 N L A S1 S:t S2 S:orks S1 R11
   date +%s|a.out -v 8001 C S11 R9 

Quickly determine size of response using R, no output

   echo http://example.com|yy025|a.out -v example.com:80 C S70 R

Send 56 byte HTTP request padded to 65 bytes

   echo http://example.com|yy025|a.out -v example.com:80 C I S65 R17

Faster without I, but unreliable

   echo http://example.com|yy025|a.out -v example.com:80 C S65 R17

Output full response

   echo http://example.com|yy025|a.out -v example.com:80 C I S65 R0

Combine R and X

   echo http://example.com|yy025|a.out -v example.com:80 C I S70 R17 Xi grep -o "<title>.*</title>"
