I need to write a program similar to a telnet server. A telnet server
asynchronously reads data from a socket and writes it to a
sub-process, and asynchronously reads data from the subprocess and
writes to a socket. My program needs to replace the subprocess with a
serial port.
The telnet server cannot anticipate when data will arrive from the
socket. Neither can it anticipate when data will arrive from the
subprocess.
How can I write a similar OS vendor neutral program using
Java or
Groovy or Jython, except, instead reading and writing to a process, I
read and write to serial port? Can I do this with a single
thread? How
do I read and write to a serial port? Can anyone point me to some
sample code for serial port I/O?
Thanks,
Siegfried
