[PD] Forwarding serial data through an Arduino (with firmata) to a serial display

[Dan Wilcox]

As you're on Linux, the port number assignment is probably tagged to the specific usb bus port and ca change.  You can have them assigned to the same serial port # each time if you create a little udev rule for both the arduino and the serial port adapter and specify what you want them to be or create a symlink to say /dev/ttyArduino & /dev/ttyLCD ...

See http://playground.arduino.cc/Linux/Udev & http://reactivated.net/writing_udev_rules.html
