It seems when using srl_read I get one of two things: the message "error:
serial: Error opening the interface: Access is denied". Or Octave will
simply not run the program and will freeze, requiring me to force close it
using task manager. Why am I getting the access is denied message? Also what
could be causing Octave to freeze in such a manner?
