Hi Folks,
i am trying to run a dos terminal program under DosBox but i get an issue.
When i load the terminal and set the parameters for the serial port,
if i just switch OFF and ON the TNC i always get the cmd prompt but if i try to digit anything,
i do not get the cmd back it is like it is blocked and also if i try to switch OFF and ON again i do not
see anything more on the display until i discharge and re load the program again.
Please any help to solve the issue?
Thanks
Enzo

I don't understand half your post. What is a "TNC"?

As discussed the last time you were here, if you are using a USB to serial connector, then that may be the cause of your problem.

Well, I'm out of ideas.

You can try using Portmon to monitor activity when you're using DOSBox and when you're using PuTTY. Perhaps the comparison will yield some clues.
