Perhaps you've got this all sorted out. If not, or for the sake of
others who might have a similar problem, here are some things to
consider.
Your program and system environment are pretty complex, giving lots
of opportunity for things to go differently than you want/expect.
I'd suggest you start with a simpler, more visible chunk:
DEBUG CR,"Begin SERIN"
SERIN 1,16884,2000,no_data,[noparse][[/noparse]WAIT("GPRMC,"}]
DEBUG CR,"Success :-)"
quit:
DEBUG CR,"Done."
END
no_data:
DEBUG CR,"Input failure :-("
GOTO quit
This will tell you if you ever get the GPRMC sentence identifier at
all. If not, you may have a baud rate problem on the sailsoft
program, serial port problems on the PC, or you may be timing out
because no data is received due to wiring problems or other gotchas.
When you get that working, add the rest of the pieces to the puzzle
back in a few at a time so you have fewer possibilities of where
any problems may be hiding.

I download a program from "http://www.sailsoft.nl/" that generates
NMEA output string to one of RS232 ports (com2) (the other is
connected on my BS2SX (com1)).
I try to take this string with the following command
serin 1,16572,2000,no_data,[noparse][[/noparse]wait("GPRMC,"),str time\6,... lonA\5,skip
1,str lonB\2,skip 3,lon_hemi]
and display it to a "debug" window of BS2SX
debug latA(0),latA(1),....,lonA(4),lonA(5),".",lonB(0),lonB
(1)," ",lon_hemi," "
goto get_data
but the program always shows nothing.
Can you help me with that?

The baudmode specified (16572) is fine for a BS-2 or BS-2e but it must be
changed
for a BS-2sx to read 16884 for it to operate at 4800 baud (presuming that's
what
you want).
Hope that helps
