Occasionally losing first character on Mac OS 10.7 about java-simple-serial-connector HOT 4 CLOSED

Have you tried to work with your code scanner in jssc-terminal placed on wiki 
page ? Send request and get answer.

Also, are you using separate_jvm key for your applet, it's very important. 

Yes.  I tried using the jssc-terminal from the Mac.  It too loses the first 
character.  What I did was bring up the terminal applet, opened the port, and 
scanned a barcode.  This worked fine.  I closed the port and refreshed the 
page.  I opened the port again and scanned another barcode.  This time the 
first character was missing.

I'm including the separate_jvm key.  When i tried to remove it I got some issue 
about the DLL being in use, so I agree that it must be important.

Turns out it was due to the driver I was using.  I had an aten u232A 
serial->adapter.  I was using the pl2303 driver from prolific.  I switched to 
an open-source driver (in case anybody else with the same issue stumbles upon 
this, its available here: 
http://changux.co/osx-installer-to-pl2303-serial-usb-on-osx-lio.  The pre-10.7 
version is available here: http://osx-pl2303.sourceforge.net/).  This fixed the 
character loss problem.

However the open source driver calls the serial port 
"/dev/tty.PL2303-000012FD".  Doesn't get picked up by your port listing.  I 
used a symbolic link to get around that, but just something to think about I 
guess.

Ok, thank you for this information. Issue closed.
