Hi,
I have an old program for data acquisition with serial cable and the program it's only work in the serial port 1 (COM1) but I need to use the second serial port (COM2) and the DOSBox fake that the program is using the COM1, sorry for my English 😅

So if I have this configuration DOSBox with:
-------------------------------
[serial]
serial1=directserial realport:com1
serial2=disabled
serial3=disabled
serial4=disabled
-------------------------------
And plug in the serial cable to the COM1 in to the PC it's working, but if I'm configuring it like that:
-------------------------------
[serial]
serial1=directserial realport:com2
serial2=disabled
serial3=disabled
serial4=disabled
-------------------------------
And plug in the serial cable to the COM2 in to the PC it's not working! Why?

Can anyone help me? Thank you!

COM1 a "real" mainboard port and COM2 USB? Or COM2 is simply broken.

Also have a look at the ports in the device manager if the 'FIFO enabled' settings differ.

1+1=10

That it's! the COM2 is broken I don't know why. I tried in another computer and it's work now. Thank you!
