Add auto-resume to downloading when a forwarding link is broken, then reconnected.

No resume when broken HF links between CMS via RMS to RMS Express?

Many times (maybe most? or ALL the times?) a broken link transfer seems to start from scratch at next connect. This also when waiting several minutes before the next try so the CMSs should be able to syncronize.

If intention is that the B2F compressed link should catch up from where it had arrived when broke, like the old FBB compressione then there seems to be a bug somewhere.

At the time beeing this again from me is a "feeling" based upon "unsystematic" observations "massaging" the LA3F-5 and LA3F.

Both when doing the Winmor 114kb file on 80m in december several times deliberately "destroing" link it started from scratch every time.

Same observation is done by my Cosysop testing a lot of P1 transfers some days ago in and out of RMS Pactor on 40m using a about 25 kb picture file. It never succeeded. Always stopped a couple of kb before finnished. PK232 on a P1,2,3 capable frequency. Shorter files did succeed.

When getting time for it we will return with Log files from all the sites doing new more systematic obesrvations.

Testing has not been done with Airmail and Paclink.

My hunch is that if there is a bug here, it may be a mission critical one in case of emergency.

Reducing unnecessary footprint is important.

When I ran a FBB setup I did see this work and I have read Ricks comments about having to save the unsent part of the message on the CMS and the problems with that but that is not how FBB did it.  The message was save as a binary file on the client in the mail.bin and then uncompressed in to the mail folder.  If the transfer was broken the portion of the received message was saved by the client.   Upon reconnection after the exchange of the MID's
the client would sent a Y xxxx    The xxxx would be the size of the binary file it saved from the first try for the message with that matching MID.
The CMS would have to be able  to  skip down to the xxxx byte and start sending at that point and the client has to append the new data onto the file it has in the mail.bin.  Seeing that the CMS is sending all binary files from the outside looking in this looks like a great way to save a lot of air time.   73 Steve N9LOH

Phil. If AirMail perhaps already has this capability in one direction, could it be worthwhile implementing similar double direction option controlled/identified by a unique letter in the MID/SID separating it from RMS Express.

Saving air time is of majour importance in time of real emcomm.
73 and thanks for the effort so far. de LA7UM Finn
