There was a post last week or so on using the HP48 calculators with a Mac, I have been playing with this for a week now.
You need a KeySpan USB to serial adapter as well as the cable for the calculator. I have a KeySpan USA-28. The latest software from them installs and behaves as they describe. In OS X, the two ports appear in the /dev directory as soon as the unit is plugged in.
If you have the KeySpan USB adapter and the latest software from them, you may be able to use AppleWorks 5 for OS 9 to link to a HP48G series. AppleWorks 5 (but not 6) had a communications module with XModem, but not Kermit. I have an HP48SX and could not test this.
I have searched for OS X applications that support modem operation and have two candidates.
One is the original C-Kermit program, but this is a terminal (no GUI) application and it is anything but user friendly, just installing it from the download takes several not so obvious commands.
Not only that, but the command to connect to the port is not accepting any of the device names I have tried. I have a trouble report open with them asking about this.
There is an alternative called PowerTerminal, and I trying to get the demo version to download, but it times out each time I try. You can find it with Version Tracker by searching for "terminal emulation".
If anyone has this or tries it, let us know. I will be trying again.
Once I get something to work, I'll be back with a post.
