We don't use Serial.readString(), that will always fail. Maybe not always, but in many situations.
You can try to send "GetTime" without Carriage Return and without Line Feed and then wait for the one second timeout.
unsigned long currenttime1 = 0;
unsigned long currenttime2 = 0;
unsigned long currenttime3 = 0;
unsigned long currenttime4 = 0;
unsigned long currenttimeA = 0;
unsigned long currenttimeB = 0;
unsigned long currenttimeC = 0;
unsigned long currenttimeD = 0;
unsigned long currenttime5 = 0;
unsigned long currenttime6 = 0;
How can you possibly need 10 variables to store now?
// if (cmd=="Help") Help();
Go ahead, jump right in, assume that you KNOW what is in cmd. I'll bet a box of donuts that you are wrong.
