I suspect MAX_TPDU_DATA value may be too high. The code seems to try to not 
send more than 4096 bytes at a time. In that, if I understood correctly, 
MAX_TPDU_SIZE should be 4089 rather than 4092.

#define MAX_TPDU_SIZE  4096
#define MAX_TPDU_DATA  (MAX_TPDU_SIZE - 4)

I am not at all familiar with the underlying standard though, so I am not 
going to change that. (This commit should not make any difference.)
