Update to the first 2017 update package

Unfortunately, I don't think I can do that. The PDF in the 2017 archive gives the same instructions:

XEQ "MMUCLR"
"YFNZ"
XEQ "PLUG1L"
XEQ "TURBO50"
XEQ "SERINI"
XEQ "BAUD48"
"830000-0FFF"
XEQ "YIMP"

And nothing happens... The display shuts off for about 1 second and I get 1.000 on the stack. No error message, no "RECEIVING" message, just back looking at the X register with 1.000 in it. I can see the PC send the data on my USB->Serial adapter LED, but the calculator is not listening for it.
