Hi I have Marlin Kimbra 4.3.6

when Serial to SD upload is started by M28 failed, there is no way to stop the upload to SD because every commands need a checksum and a line number which is not easy to calculate manually when you want to cancel a faulty transfert

M29
Error:No Checksum with line number, Last Line: 0
Resend:1
wait

I think M29 should be an exception of mandatory checksum, if not, the only way to recover of faulty Serial to SD is to restart printe,r which is little bit hash...

FYR same issue happen to Marlin (MarlinFirmware/Marlin#11871) but not on Repetier
