The Arduino ide prefers to use the cu.usbmodem* and some of the tests I have done in LC have shown that the tty.usbmodem* is the better choice for receiving data from the Arduino Uno and the cu.usbmodem* when trying to send. I am not sure what the difference between the two of them are and why LC prefers the tty for receiving and the cu for sending??? And my test are suspect to begin with due to a lack of understanding at the start into this wonderful world of serial communications.
I don't have much experience with UNIX drivers, or how they're named. I can guess what tty is short for, but no clue about cu. As for the chars at the end (like 3d11 or 3a21) are those identifiers assigned by UNIX to be sure each driver is unique? I know that happens with disk names, but its just a guess here. Over to you, UNIX guts gurus!
