Original description
What change would like to see?
Using a patched rxtx library (and os specific ports) to reduce the serial latency. per default, the rxtx library notifies about serial events each 20ms. this sounds sound fast, but if you need to send alot of data to the arduino via serial port this is too much.
method to patch:
SerialImp.c:
void report_serial_events(...
replace the "usleep(20000);" with "usleep(2000);" or even lower.
there are also a lot of fixed issues in the rxtx bugzilla (http://bugzilla.qbang.org/buglist.cgi?regetlastlist=1)
check http://neophob.com/2011/04/serial-latency-teensy-vs-arduino/ for more details about the latency
Would this cause any incompatibilities with previous versions? If so, how
can these be mitigated?
I dont think so...
