API - 1 or API -2 in series 2 ?

, , ,

which api mode i want to choose 1 or 2(with escape characters)?

i dont know the difference between the two .

is api 2 is more reliable that api 1 ?if yes how ?

please help.

No, API mode 2 is not more stable than 1. The only real difference is that some applications have issues with receiving bytes that should be used for software flow control within the data payload. When working with these types of applications, API mode 2 is preferred. The reason for that is that API mode 2 escapes the data that could be misunderstood as flow control bytes thus allowing the data to be received and processed as data.
