I did some spelunking this morning in the comp.sys.hp48 newsgroup and came across this thread that essentially announced an alternate version of Conn4x (with what appears to have an earlier build number than the "official" release, despite it being newer). I can confirm that this build 2361 version is able to successfully complete the backup process with my 48G.

There's a wrinkle, however. Bill's suggestion to simply rename the original version and likewise rename his alternate one as "Conn4x.exe" didn't work for me. I had the same result as several others in that thread (various exceptions and memory errors). Following the advice of one of the posters in that thread (Steve R.), I simply left the b2361 version named the way it was and ran it from the same location. At that point everything worked as it should with the XMODEM server running on the 48G.

So it's not a very pretty solution, but it does at least allow you to successfully make a backup using the tool you're already familiar with. Hopefully this will get you going!
