The symbol in the schematic is an off-board connection (either a connector, wire, or the like). The top two (home#1 and home#2 are signals from switches (in this case optointerruptors, but could me mechanical) that tell the processor when the motor is in its home or 0 position. The bottom two are TTL (5V) level serial communications to whatever is going to control the motor.
