PORTWRITEARRAY count buffer

PORTWRITEARRAY writes to the currently open port with the data in buffer, which must be an array of byte-sized integers. It attempts to write count bytes to the port, if possible. PORTWRITEARRAY outputs 1 on success and 0 on failure.

If count is larger than the size of the buffer array, then the entire array is written.
