4.2 UART Interface
The UM01-HW UMTS module has one UART interface, that is, UART1. UART1 is a 9-wire
serial interface supporting the flow control function and a maximum transmission rate of
230.4kbit/s.

UART1 supports data services. You can set up the Point-to-Point Protocol (PPP) dial-up
connection for data services through UART1.

UART1 supports programmable data width, data stop bit, and parity check (or no parity
check). In addition, UART1 supports a maximum baud rate of 230.4 kbps and a default baud
rate of 115.2 kbps. The set baud rate can be saved even if the interface is powered off.
