  4. Description of your issue:

old serial GPS not found (baudrateError)

in main/gps.go: func initGPSSerial() bool {}

the GPS is initialized with 4800baud then it is tested if it is a SIRF IV or something other... if it is NOT a Sirf IV there will be send a few magic numbers and then the baudrate is set to 38400 but there is no test if the GPS-chip does understand the "change the baudrate message".

My old Sirf II does work well on 4800 and if I comment out the else{} of if isSirfIV {} the Error has gone

Sounds like you have found a solution that works for you. The older Sirf II isn't supported hardware, so I don't think we'll add any fixes to the code for this.
