HI Shamil,
This is not possible since the context is lost on hibernate.

ok, fine!

1) how can i get handle of soket by SDK methods?

2) How can i get sequence number from last incoming frame? Or? how can i get access to all incoming bytes in tcp streaming except message bytes?

3) And, how i can save something in external memory? Are there methods in SDK to read/write in external memory?

1) you will have to store the handle in a variable (don't lose it)
2) you cant get the TCP seq, but you can implement your own numbering scheme/protocol
3)it depends on the external memory. To use the connected serial flash, there are fs API calls. See the NWP manual for using the NWP filesystem
