HP 48G+ over 50G?

Launch Datacomm on the 200LX (probably works on the 100LX and 95LX too), and configure it the same way via Connect, Settings. Go to File, Protocol, and choose Kermit. Then do File, Receive, and enter a filename (save straight to a: if desired).

On the 48, do something like this to start the backup:

:IO: 'BACKUP.48G' ARCHIVE

That's the basic idea, anyway. If you want to include things that ARCHIVE doesn't send normally, write a program that saves your flags/user keys/alarms to variables before calling ARCHIVE.

Sometimes it can be a little fiddly to get connected. You might have to remove the IR port covers, or place the 200LX on a thin book to line it up better. Once it's running properly, you're usually fine. If you have trouble getting it working, play around with the baud rate. Once the ports/settings/planets are properly aligned, it works reliably, though a bit slow, given the low baud rate, and slow sysrpl kermit implementation in the 48.

Can't remember if I tried this with my Omnibook 300, or what the results were. I know I got the 300 and 200LX talking via Laplink over IR.

I played a bit with HP200LX and HP48G+.
It works on 2400 baud, 8 data bits, 1 stop bit, no parity..
Quite slow, but works. Does the job, now my HP200LX is no more a doorstop

Thanks Dave,
