higher number, or use a Putty terminal just to see which one outputs weird binary data (or Port 30003
format if selected). The one that outputs a console screen on 115200 Baud is the wrong one.

Some usage and driver hints - this is where the INF file comes from.
Restrictions
1. Currently the serial interface worked with Putty and a test application on Windows. It did
not work with Planeplotter under XP, so don't blame me at the moment.
2. Note that even when a Radarcape receives power through the backside USB, you
anyway need to connect the external +5V for the receiver and decoder to operate.
3. Also note that when powering on, USB must not be connected first before external +5V,
as then the Radarcape will power on with low CPU clock settings.
Port 30003 Server
Port 30003 style output (e.g., SBS Plotter) can be provided standalone and without need of a PC
application.
The date in Port 30003 messages is always the Linux system date. The timestamp instead is a GPS
timestamp when the config is set to GPS timestamps and system time when the Radarcape operates in
legacy 12MHz timstamp mode.
