DM-41

[Jurgen Keller]

I played around with the serial console functionality. I can backup the DM-41 and restore it using the 'Dump Memory' and 'Load Memory' commands. I've used Tera Term on my Windows 8.1 PC (PuTTY doesn't work on my computer for unknown reason). However, the en/decode utility doesn't (yet) support the DM-41 so you cannot easily transfer programs to the HP-41. You have to type it in, and that's a little painful and might cause finger spasms ;-)

I also wanted to know if synthetic programming works. I could create a byte grabber and typed in the Westminster Chime program. Unfortunately, two of the synthetic tones do not sound right, they just cause a long and low buzz.

Another thing I've noticed is that the Master Clear (pressing ON+[<-]) doesn't work. A workaround is to go into serial console mode, execute the 'Load Memory' command and press RETURN on the PC (i.e., loading no data). This will cause a MEMORY LOST when you leave the serial console mode on the DM-41.
