I have a unique application that will require some creative configuration of two serial ports on an embedded system. I haven't chosen a target board yet so I'm open to recommendations (low power, 2 serial, and 2 Ethernet req'd).
On one serial port there will be a MODEM and on the other serial port a device that is capable of dialing out. When I dial into the MODEM I would like for the the embedded system to act as a Dial-In Server for two other devices connected to the Ethernet ports. When the device on the other serial port dials out I would like the embedded system to "echo" or pass the serial communication through to the MODEM on the other serial port.
So the embedded system will serve two functions.
- Dial-In Server
- "Serial Communication Valve" allowing unhindered communication in one direction and using the opposite direction for the input to the Dial-In Server.
Is this possible?
If so, how difficult?
Thanks,
John
