// = .42 seconds for the longest sentence to be fully transmitted
// and then it may have to do something like erase flash before replying...

// at low baud rates and high data rates the ubx gps simply must drop some outgoing data
// and when a lot of data is being dropped, the MON VER reply often gets dropped
// on the other hand, uBlox documents that some versions discard data that is over a second old
// implying that it could be over 1 second before a reply is received
// later versions dropped this and drop data when the send buffer is full and that could be even longer
// rather than have long timeouts, we will let timeouts * retries handle that if it happens
