All flow control handshakes are supported by the UART interface and can be set by appropriate AT
commands (see
u-blox AT Commands Manual [2], &K, +IFC, \Q AT commands): hardware flow control
(RTS/CTS), software flow control (XON/XOFF), or none flow control.
Hardware flow control is enabled by default.
The following baud rates can be configured by AT command:

2400 b/s

4800 b/s

9600 b/s
 19200 b/s
 38400 b/s
 57600 b/s
 115200 b/s, default value when the autobauding is disabled
The following baud rates are available with autobauding only:
 1200 b/s
 230400 b/s
Autobauding is enabled by default.
The following frame formats can be configured by AT command:
 8N1 (8 data bits, No parity, 1 stop bit), default frame configuration with fixed baud rate
 8E1 (8 data bits, even parity, 1 stop bit)
 8O1 (8 data bits, odd parity, 1 stop bit)
 8N2 (8 data bits, No parity, 2 stop bits)
 7E1 (7 data bits, even parity, 1 stop bit)
 7O1 (7 data bits, odd parity, 1 stop bit)
Automatic frame recognition is supported and enabled by default in conjunction with the auto-
bauding. When auto-bauding is active, the auto-framing is enabled overruling the frame format
setting.
Figure 16Figure 16 describes the 8N1 frame format, which is the default configuration with fixed baud rate.
