Serial Problem - Handshaking maybe?

I've been working on a project to control some LEDs from music, with a Microchip chip acting essentially as a serial (over USB) to SPI interface (yeah I know I should probably just get an audrino board...its on my list). So I have a sketch that can generate the values I'm looking for from an audio source but the serial communication appears to not work at all.
To troubleshoot, I modified the simple serial write example and attached a port monitor to see what was going on. The part I can't get past is that sending the same characters through a terminal as with the test sketch (verified as identical with the port monitor), the hardware responds correctly to the terminal characters but ignores the ones sent with processing. I know its not a hardware problem because I have a number of VB programs that interact with it fine, so I'm thinking, does the processing serial library have any kind of handshaking defined that could be throwing things off?
(sorry for the long explanation)
