#1
The readline() method in pyserial reads one character at a time and compares it to the EOL character. You cannot specify multiple characters as the EOL. You'll have to read in and then split later using string.split() or re.split()
pyserial中的readline()方法一次读取一个字符并将其与EOL字符进行比较。您不能将多个字符指定为EOL。您必须先读入然后使用string.split()或re.split()进行拆分
