15.17 UART module
The UART module provides direct access to the serial hardware on the Q4000/QPRO.
Application access to the serial ports should be made through the SERIAL module, described in
Section 15.15. SERIAL allows the foundation firmware to exercise more control and oversight.
For those applications requiring more direct access, the public API to the UART module is
UART_ioctl()
, which allows the parity, stop bits and baud rate to be set for serial ports.
15.18 UTL module (Utilities)
The UTL module proves a number of utility functions. Some allow manipulation of the QUAKE
software counters and timers, such as
CNTR_set()
, and
CNTR_read()
or the system’s real-
time clock, such as
SYS_readSeconds()
. The API Function Reference should be consulted
for a current list with complete descriptions.
15.19 VSWR module (Voltage Standing Wave Ratio)
The single public API in the VSWR module is
ANT_readVswrOrb()
. This reports the last
VSWR reading of the ORBCOMM antenna. Notes in the API Function Reference give details on
interpreting the reading.
