System requirement:
The proprietary hardware should be able to send and receive text data, most
likely in xml format, to our corporate Mina Server behind firewall.
Server environment:
Mina Server running on Linux server located behind corporate firewall.
Client environment:
Proprietary hardware connected to a Windows PC using RS232 serial connection.
The Windows PC will have either a dial-up /dsl internet connection. The
proprietary hardware always initiates the message.
My current thoughts:
Install a Mina SerialConnector component on these client systems (Windows PCs)
which will listen for data coming through the RS232 connector. When the serial
IoHandlerAdapter receives a server message/request, it send that information to
our server using a SocketConnection and wait for the response. Once the server
response is received, write that back to the serial port.
Concerns:
I will have to open up the server port on firewall to outside world, which
might not be acceptable to the security administrator. In that case, I might
have to move the server in front of the firewall.
Any suggestions on how to design and implement such a system would be greatly
appreciated.
Does any one have any examples on how to read and write to a serial port?
