Description

Cfg_type

Bit 0

The termination type configured for the port is not valid.
Values between 0 and 15 are the only ones valid. The
module will use type 0 (stream mode) for the port.

Cfg_Baud

Bit 1

The baud rate entered for the port is not valid. The module
will use 9600 baud for the port.

Cfg_Parity

Bit 2

The parity value entered is not valid. Values between 0 and
4 are accepted. The module has set the parity to a value of
none (0).

Cfg_DataBits

Bit 3

The number of data bits for the protocol is not valid. Values
between 5 and 8 are accepted. The module assumes a
value of 8 data bits.

Cfg_StopBits

Bit 4

The number of stop bits for the protocol is not valid. Values
of 1 or 2 are accepted. The module assumes a value of 1
stop bit.

Cfg_Handshake

Bit 5

The handshake code for the port is not valid. The value
entered must be in the range of 0 to 3. The module assumes
a value of 0 (no handshaking).
