RE: HP48G Connectivity Method in 2022
Hello Mark:

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

Thank you,
TomC

On both a 2015 Intel MacBook Pro and 2021 Apple Silicon MackBook Pro running macOS Monterey 12.6 you can use the original command line c-kermit or Hoppi.

I use a StarTech.com 1-Feet USB to RS232 Serial DB9 Adapter Cable with COM Retention ICUSB232PRO, available from Amazon, to connect to the HP48GX serial cable. On the older Intel Mac this plugs straight into a USB-A port, on the newer Mac I add a simple USB-A to USB-C converter (Anker or others).

Hoppi does not need any special configuration, other than to select Serial rather than USB. My ~/.kermrc file for c-kermit is:

Code:
set port /dev/tty.usbserial-0001E6FD
set modem type direct
set speed 9600
set carrier-watch off
set flow none
set parity none
SET CONTROL PREFIX ALL
SET BLOCK 3
SET SEND TIMEOUT 20
SET SEND PAUSE 100
binary
