[gpsd-dev] gpsmon stop after 16 seconds... |

Hello,
i have a small module, that spits out NMEA0183 position sentences (GPGGA,
GPZDA, GPRMC, and GPGLL).
The module is connected via a FTDI FT232R chip to a linux system, the module
supply the data at 4800 baud only.
I try to monitor the data with "gpsmon /dev/ttyUSB0".
Gpsmon sync into the data stream, and display the data from the module, but
after 16 seconds, it stops monitoring the data.
I have started gpsmon with a high (99) debuglevel and write the data to a
logfile.
I see in the logfiles, that gpsmon try to switch to 9600 baud after 16 seconds.
Why gpsmon try to switch to another baudrate (9600), and never recover?
I do not observe this behavior with an older (2.96) version of gpsmon.
If i terminate gpsmon with crtl-c, a cat from the port shows the data again, in
some cases i need a
stty speed 4800 -F /dev/ttyUB0
or even a
stty sane speed 4800 -F /dev/ttyUSB0
