Is there a method of writing and reading an HP41 program using the HP-IL module to an RS-232 port connected to an IBM-PC, so it can be recalled into calculator memory?
I am looking to replace my aged cassette tapes and card reader with storage on a CD-R, so I'd like to find something equivalent to WRTP and READP that would work over the RS-232 link. Perhaps a binary image could be written using synthetic programming and the PPC-ROM?

Yes. You can use the Extended I/O HP82183A. The functions INP and OUTP are made for that. I use mine with an HP82169A IL/IB interface and HP82335A on PC. I recover or send data to/from PC using HP Interactive HP-IB software. But with HP82164 RS232c interface, you can use Win 3.1 Terminal.exe, Procomm, ...

Many thanks for the tip on using INP and OUTP!

First set your HP82164A and Procomm lines correctly

Hi Emmanuel,

I think the buffer of HP82164A is too small. Please take a speed under 9600. Try 4800, 2400, 1200, 600 and worst 300. Let me know if OK.

You might want to turn on flow control on both ends. This is text from Tony Duell's lifutils hardware setup instructions.
Configuring the interfaces Give this a try. I use my PC with Linux and Tony's lifutils as my storage system for my 41 and 71. Works a treat. Good luck Chris

I dropped the speed of the interface to 300 baud, and now see GOTO, PACKING, TRY AGAIN when I try to receive the hex file.

You have not enough place in your program memory.

Looks like the problem with INP is I'm getting a corrupted download. I tried importing a much smaller hex file at 300 baud, N, 8, 1, the SETRS program that Chris gave as an example (Thanks Chris!), and a few lines were received ok, but there were numerous extra lines with extraneous commands. |
