Details
This function reads available characters from the serial port. It does not wait for new characters to
arrive. As long as
maxchars
is less than 200 characters, all characters that are received by the serial
port (before the
serial.read()
command is executed) are returned. If too many characters are
received between calls to this function, the RS-232 buffers will overflow and some characters may be
lost.
Call this function as many times as necessary to receive the required number of characters. For
optimal performance, use a small delay between repeated calls to this function.
The data returned is the raw data stream read from the port. No characters, such as control
characters or terminator characters, are interpreted.
If you attempt to use this function when the serial port is enabled as a command interface, a settings
conflict error is generated.
Example
data = serial.read(200)
print(data)
Read data from the serial port.
Output:
John Doe
The above output indicates that the string "John
Doe" was read from the serial port.

No terminator characters are added to the data, and data is written exactly as specified by the
