I/O 1
will select the I/O routines defined by location E5 on page 00. Location E6 on page 00 will also be modified indicating that the current I/O is pointed to by location E5. Remember that when the I/O statement is executed BASIC first calls the initialization entry point of the I/O routines. In the case of shifting to a set of serial I/O routines this could mean the necessity for keying a RETURN to initialize the baud rate.
