Category   :Pascal
Platform    :All
Product    :Turbo Pascal  4.0+

Description:
Q. The Async routines in the manual do not work.  Why?
A. The Asynchronous communications routines in the manual do not
   provide buffered communication. In other words, if you are
   not actively reading the serial port you will only get the
   last character that arrives.  For example, if the characters
   ABCD come across the line and then you read the serial port,
   you will get back D but not A, B, or C.  TI407 provides
   buffered input from a serial port.
