question: Does your controller handles SREJ frames? #14

Closed rmcavalcante closed 2 years ago

Hello guys,

First of all, let me thank you for your work. It is nice to see initiatives like yours. I have a situation where a series of frames are sent with segmented data in another layer. One of these frames is rejected and a SREJ is sent back to me. I would like to know if your controller handles SREJ and does re-transmission automatically.

BR,

Roberto

Hi,

Thanks for your nice words!

Unfortunately no, this HDLC controller does not support SREJ frames, only the ones supported by python4yahdlc which, in turns, only supports the ones of yahdlc:

The supported frames are limited to DATA (I-frame with Poll bit), ACK (S-frame Receive Ready with Final bit) and NACK (S-frame Reject with Final bit).
