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.

Hello,
thanks for your reply.
TNC is a Terminal Node Controller and it communicate with the PC through Serial Ports.

It is not a USB to serial connector but a real serial COM1
Thanks

I still don't understand what you are trying to do.

Can you communicate with this device with a standard Windows terminal program?

Okay. And what line are you using in your DOSBox.conf for your serial port?

Are you using the latest DOSBox 0.74-3?

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.
