Just wanted use today the transcript tool program INOUT.

Got the following error message:
TRANSIO ERROR:
Invalid IOPAR

I checked then the reserved variable IOPAR.
Its contain is the following:
{115200 External External... External},
with the term External repeated 936 times.

I looked on Interned, certainly too quickly, but could not find any solution to my problem.

Could somebody help me restore the original content of that variable? And where should I place it?

Of course, I wish not to loose my programs.

Just for your information, I do not have a real HP50G calculator, but the Emu48 version working on a Samsung Galaxy S6.

Thanks for your help.

I can't say if this is the default value, but on one of my 50g's, IOPAR is set as follows:

{115200 0 0 0 3 1}

hth

It worked.
Thanks your help.

The 50g AUR (pp. D4–D5) confirms those are the default I/O parameter settings.

Those settings correspond to:

115200 baud rate
0 no parity
0 XOFF/XON software flow control disabled for receive
0 XOFF/XON software flow control disabled for transmit
3 3-digit cyclic redundancy check for SEND
1 translate 10 (LF) to/from 10 & 13 (LF & CR)

Thanks. I could not recall what the 'extra' zero is for, I forgot or maybe never realized the flow-control could be enabled only 1 way (which seems kinda strange to me...)
