HP48G Connectivity Method in 2022

[TomC]

Thank you all very much for your comments and findings.

I am currently having flashbacks that there was some special handling on the HP48 for backing up - recall ARCHIVE and RESTORE. I believe these commands are limited to Kermit protocol.

More investigations ongoing.

Cheers,
TomC

This is very interesting. I am curious how one would then perform a backup of the connected calculator.

Thank you,

To backup main memory put c-Kermit into server mode on the Mac, or simply start Hoppi, and use this program on the 48 to create a backup file called ARCMEM:

Code:

<< :IO: ARCMEM ARCHIVE >>

Replace ARCHIVE with RESTORE to restore the backup to the calculator.
