Download the dwl application with only rx and tx ua

@I

the XMODEM protocol should ensure that bad data is detected & rejected.
Also, the XMODEM protocol does not allow the next block to be sent until the previous one has been ACKed - so it effectively has its own built-in flow control…

Despite this, it does seem that the Wavecom download does require the use of hardware flow-control - especially when using 1K-XMODEM

So, this appears to be a fault in Wavecom’s XMODEM implementation?

Open AT Fan was right:

@OpenAT_Fan

downloading is a critical process which will require flow control capabilities (so that wrong data is not written).
