possibility of Arduino interfacing with both a transmitter and the computer

Using Arduino Networking, Protocols, and Devices

Hey there,

Could I ask if it is possible to directly interface with both a connected to a radio transmitter and the computer (via the USB cable), using the Arduino Uno?

I currently have 2 Arduino Unos. Am planning to send radio signals to one Uno (acting as the receiver), using another Uno (acting as the transmitter). The transmitter Uno should receive commands from a computer (using the Screen program on Linux).

Is that possible?

Yes, it is. The radio transmitter or receiver could be connected to two pins as a software serial port, using NewSoftSerial (0023 or earlier) or SoftwareSerial (1.0 or later).
