[comp.sys.laptops] serial port question

I just received the new DataWorld NB320sx, and so far it looks nice.
I have not tried any real dos software, but I have looked over the
features and read all the manuals. It is 20 MHz, 386sx, VGA,
20Mb HD, 3 1/2 floppy, etc... etc... etc... 

The ad says 6.5 lbs with battery, but my scales say almost exactly 7 lbs.

The power adapter is small and light.

The screen is fairly nice, but there are some areas near the edges that
are a bit lighter than the rest.  It has suspend mode.  It has 4 SIMM
sockets, so will take up to 16 Mb of RAM.  Mine came with 4M.
It will take a 387 coprocessor, and an internal modem.  DataWorld
claims that when the larger Conner drives becomne available, the
20 Mb HD can be replaced with no problem.

Here is the question... on the back are one parallel port and 2 serial
ports (COM1 and COM2).  If the internal modem is installed, the manual
says that COM2 will be inoperable.  The modem occupies a different area
of the box from the COM2 port.  SO, is this a DOS weirdness, or are there
other notebooks out there that have two working serial ports when the
internal modem is installed?
