Which library to use? running out of pins with Serial.begin...

Using Arduino Programming Questions
#1

please help a newbie out... Which serial library should I use if i cant give up 2 pins for serial communication? I only need TX, not RX. I cant use Serial.begin, because it sucks up 2 pins.

I am going to add an ethernet card to my arduino, and thus I am running out of pins on my little experiment.

Is there a serial library that allows the arduino to only use one pin for serial TX, and not burn another pin for RX (when RX capability is not needed?)

I'm not sure there is, but you could take SoftwareSerial and chop out the parts that do the receiving.
