Hi, any reason you wouldn't use something like rxtx, which is basically serial communications for java? Marc

Hi All,

I am new in jna, sorry for stupid-like questions. I would like to handle serial port under debian linux testing with jna based on this sample: http://www.comptechdoc.org/os/linux/programming/c/linux_pgcserial.html

Yes, I know rxtx is a good solving for this, but rxtx has a big latency after read char to data_available signal (cca. 5ms). This native c latency time is 50uS! I would like to check it with jna.

in shortly: open port with fopen get attribs with tcgetattr set attribs with tcsetattr set signal handler

my first question: - how can I call fopen, tcgetaatr, tcsetattr and so on, because these are simple system functions, not a .so library functions. -- thx, ---------------------------------- Zoltan Zidarics programmer PTE-PMMFK H-7621 Pecs, Boszorkany u. 2.
