+Serial Support
+--------------
+
+The default DOS serial driver does not support speeds above 9600 baud. For
+higher speeds a more capable serial driver (like ADF) must be used.
+
+
+USB Support
+-----------
+
+USB is not supported.
+
+
+Bluetooth Support
+-----------------
+
+Bluetooth is not supported.
+
+
+Compilation
+-----------
+
+The MSDOS version can be compiled thanks to a cross-compiler. Get the following
+archives:
+
+   ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/gcc410s2.zip
+   ftp://ftp.delorie.com/pub/djgpp/current/v2/djcrx203.zip
+
+The djcrx203.zip archive contains a file named cross/howto.32 which explains
+how to build a cross-compiler for gcc 3.2. You can build one for gcc 4.1 by
+applying the same instructions to the gcc410s2.zip archive (listed above)
+instead of to the gcc32s2.zip archive (mentioned in the howto). You can also
+use a more recent binutils package too (2.16.91 works fine).
+
+You can use the cross-compiler with the following ./configure command:
+
+   CC_FOR_BUILD=gcc LD=i586-pc-msdosdjgpp-ld ./configure              \
+      --prefix=/brltty-msdos                                          \

+      --build=x86_64-unknown-linux-gnu                                \
