| You need to create data packets. This will allow you to separate the data into strings. For example you choose characters that you wont ever send in your strings. Use them as start and end of packet.. like this ~ = start; ^ = end. Now your packet can look like this: ~First String^ next packet: ~Second String^. Now you program can find the begin and end of each string easily.

You can do it by atleast two ways ....... as follows -
1. you can go for adding Header and footer as told by Mr.davidgrm,
and for Reliability and accuracy you can go for addition of CRC or Checksum.
2. you can limit your input buffer useing time limitation or character limitation
But I think it will be better to go for the first one , because in 2 nd one character loosing probability is higher than First one .
OK ..... best of luck and Good Bye .....
