SERIN2 - "Timeout" hangs if > 255

[flotulopex]

Thanks mackrackit,

For info, my GPS module sends data @ 1Hz interval. As long as I set my timeout value < 255, the expected result will occur.

Are your saying that timeout will not work if the expected character string OR any signal is received whithin the timeout value? I'm confused.

I use this modified (in red) routine to check if a particular NMEA sentence is sent by the GPS module. In that way, SERIN2 will receive signals and still have the timeout (<255) working - or is this test not valid?

CHECK_GGA:
SERIN2 GPSfrom,Gpsbps,Timeout,NoGGA,[WAIT("$GPxxxGGA")]
GOTO GPGGA:
NoGGA:
LCDOUT $FE,2, "no xxx"
PAUSE 500
SEROUT2 GPSto,Gpsbps,["$PSRF103,00,00,01,01*25",13,10]  'set ON GGA
GOTO CHECK_GGA:
GPGGA:   'start the next step....
