can't work fine with new version

[lingfengchencn]

Hi , thank you for this repository. now, I can't use it to decode the new log file.

can you tell me, how to decode it? thanks.

for example:

control code :	0x20
frame len : 	9
 
control code :	0x39
frame len : 	48
 
control code :	0x19
frame len : 	28
