Transfer of programs between 41CX and Windows XP computer Message #1 Posted by Prabhuraj Bhooplapur on 7 May 2006, 1:21 a.m. I have a HP82164A - the HPIL to RS232C interface. I would like to know how one could transfer programs from HP41CX/HP41CV/HP41C calculators using this interface to a Windows XP Personal Computer. Thanks for your responses. Prabhu

Re: Transfer of programs between 41CX and Windows XP computer Message #2 Posted by Eric Smith on 7 May 2006, 3:41 a.m., in response to message #1 by Prabhuraj Bhooplapur Depends on whether you want to get it into the PC as text, or binary. I don't recall the exact details in either case, and I don't have the 82160A manual handy, but if you've got that it's fairly easy to work out. For text, you select the 82164A as a printer (make sure the printer ROM enable switch on the bottom of the 82160A HP-IL module in the 41C is turned on, and that you don't have an 82143A printer or 82442A I/R Printer Module installed), then use the "PRP" command. For binary, you need the Extended I/O Module. You address the 82164A as a listener, then use the "OUTP" command, with the name of the program in the alpha registers. Note that the output isn't raw binary, it's encoded as hexadecimal characters.

I will try and let you know. How is my windows pc recognised by the HPIL-RS232C interface? Do I have to set up some sort of emulation?

If anyone have an idea ....... Regards Francois

Re: Transfer of programs between 41CX and Windows XP computer Message #5 Posted by Emmanuel on 8 May 2006, 6:31 p.m., in response to message #4 by Francois In order to transfer programs to PC and receive them from it, I use the Extended I/O INP and OUTP functions, and a Terminal software (Procomm in binary mode transfer for instance). Yours.

Re: Transfer of programs between 41CX and Windows XP computer Message #7 Posted by Doug Wilder on 9 May 2006, 4:14 p.m., in response to message #5 by Emmanuel XP has a programn called HyperTerminal to talk to serial port. Sending data PC->HP41C needs protocol (XON/XOFF) set in HP82164A, namely R11=8, which requires XIO or IL-DEV module or an MLDL. Hardware: PC is a DTE, use something like 25in-9pin as here: http://www.cablewholesale.com/catalog/nullmodemcables.htm Edited: 9 May 2006, 7:09 p.m.
