#Serial? 80C186E? 100#
This serial channel has five modes of operation, and you have selected the
Synchronous Mode (Mode 0).  In Synchronous Mode, the serial controller
generates a clock on TXD and uses RXD to transmit or receive data.
#Serial? 80C186E? 101#
This serial channel has five modes of operation, and you have selected the
10-bit Asynchronous Mode (Mode 1).  In this mode, a 10-bit frame is required
for transmission and reception.

The frame consists of one start bit, one stop bit, and 8 data bits.  The eight
data bits can optionally be configured to be 7 bits of data plus parity (see
Parity Select).
#Serial? 80C186E? 102#
This serial channel has five modes of operation, and you have selected the
11-bit Asynchronous Mode with Address Recognition (Mode 2).  In this mode, an
11-bit frame is required for transmission and reception.

The frame consists of one start bit, one stop bit, and 9 data bits (eight data
bits plus RB8).  The unique feature of Mode 2 is that reception does not
complete unless RB8 (the ninth data bit) is 1.  Mode 2 (along with Mode 3,
11-bit Asynchronous) is used when multiprocessor communication is required.
Refer to the manual for complete details.
#Serial? 80C186E? 103#
This serial channel has five modes of operation, and you have selected the
11-bit Asynchronous Mode (Mode 3).  In this mode, an 11-bit frame is required

The serial channel has five modes of operation, and you have selected the
9-bit Asynchronous Mode (Mode 4).  In this mode, a 9-bit frame is required for

The frame consists of one start bit, one stop bit, and 7 data bits.  Parity is
not available in 9-bit Asynchronous mode.
#Serial? 80C186E? 105#
Please enter the desired baud rate.  For example, to configure the serial
channel for 1200 Baud, enter '1200' here.  To have the serial channel operate
at 19.2 Kbaud, enter '19200'.

The value you enter here, together with the CPU clock frequency (or BCLK
frequency), determines the value to be programmed into the baud rate
generator.
#Serial? 80C186E? 107#
Check this field to enable the Clear-To-Send (CTS#) feature of the serial
channel.

The Clear-To-Send feature is used to control the transmit portion of the
serial channel.  When Clear-To-Send is enabled, no transmissions can occur
until the channel's CTS# pin is active.
#Serial? 80C186E? 108#
Check this field to enable the serial data reception, or clear this field to
disable serial data reception.

Use this field to disable the receiver when you do not wish to have the
