Kevin,

 

No, I'm not getting consistent amounts of bytes. They vary from 0 to over a hundred.

Hey Jose,

If you know how many bytes of data you are expecting to receive I would set up your code to wait (at least up to a certain timeout) until there are that many bytes at the port.  It seems like you may just not be waiting long enough after the write to perform your read.
