Timeout support for RXTX OutputStream.write()

[Ralph Lecher]

Hi!

With the RXTX Comm API is there a way to avoid OutputStream.write()
blocking the application if the targeted serial device doesn't take
over the offered data. I only found SerialPort.enableReceiveTimeout(),
which I hope prevents at least InputStream.read() from heading towards
Nirvana.

TIA

It shouldn't block which just shows that RXTX has numerous bugs. Use
Sun's JavaComm API. They support the Linux version and the Windows
version still works fine (at least on XP). Your only other option is to
buffer it.

If you're stuck with RXTX, you might like to look at the project's
transport layer, which uses RXTX for serial I/O:
