FLOWCONTROL.C
Serial Port F for CTS/RTS with serial data coming from TxE (Serial Port E) at 115,200
bps. One character at a time is received and is displayed in the
To set up the Prototyping Board, you will need to tie
TxE and RxE together on the RS-232 header at J14,
and you will also tie TxF and RxF together as shown in
the diagram.

PARITY.C
byte values 0–127 from Serial Port E to Serial Port F. The program will switch between
generating parity or not on Serial Port E. Serial Port F will always be checking parity,
so parity errors should occur during every other sequence.
To set up the Prototyping Board, you will need to tie
TxE and RxF together on the RS-232 header at J14 as
shown in the diagram.

sequence.
SIMPLE3WIRE.C
Lower case characters are sent by TxE, and are received by RxF. The characters are
converted to upper case and are sent out by TxF, are received by RxE, and are displayed
in the Dynamic C
To set up the Prototyping Board, you will need to tie
TxE and RxF together on the RS-232 header at J14, and
you will also tie RxE and TxF together as shown in the
diagram.
SIMPLE5WIRE.C
by providing flow control (RTS/CTS) on Serial Port F and data flow on Serial Port E.
To set up the Prototyping Board, you will need to tie
TxE and RxE together on the RS-232 header at J14,
and you will also tie TxF and RxF together as shown in
the diagram.
Once you have compiled and run this program, you can
test flow control by disconnecting TxF from RxF while the program is running. Char-
acters will no longer appear in the
connected back to RxF. (Do not disconnect the data path between TxE and RxE.)
