CMD.EXE is a text-mode application.  It is designed to run in OS/2's
full-screen text mode.  The windowed sessions are simply emulated text
modes.  They have a fixed size (settable via the MODE command).

Sun's (and X) windowed sessions are different.  Unix is generic enough
to run its shells on anything.  They only assume the most basic
functions (newline, maybe backspace), with everything else defined at
run-time (via the termcap file).  They make no assumptions about the
system.

CMD.EXE assumes quite a bit.  As do most text-based OS/2 programs.
Therefore, the text sessions are designed to accomodate this.
