There's no such functionality built-in, but you can switch to different text modes manually - there was a post about it some time ago (I can't find it now), and in there ripsaw8080 posted a set of utils to change to various modes. Just run e.g. 80x50.com and you're done (you can add it to autoexec section of your .conf file, or add these utils to PATH variable inside DOSBox).

There's a small problem, though: DOSBox built-in cls command resets the text mode back to 80x25; attached textutils include clr.com program, that provides the same functionality without resetting mode.

dreamer, thanks a bunch. The utils you pointed me to are very helpful.

there is a tool called "tm.com" and you run tm 25, tm 28, tm 43m tm 50

I recently installed Dosbox on a Linux Mint 19.1 system, and I noted that it contains 25 screen rows when I run it. Is there any way to have Dosbox display more than 25 screen rows?

Worth mentioning that the text mode screen in DOSBox isn't a terminal like you're used to (like xterm or what-have-you), it's emulating the video output of a DOS PC, that just happens to be displaying text at startup.

DOS doesn't buffer the text bring written to CON: so without third-party software, there is nothing to scroll back to.

You might know this already, but it mightn't be obvious to people who are accustomed to modern terminal apps.
