Porting cbmlink to MS-DOS

I ran across to a small 8086/80386 C compiler called bcc, where the B 
stands for Bruce Evans and not Borland.  The compiler is freely 
available in source code form under the GNU General Public License, 
which makes it an excellent choice for open source projects.

I created a cbmlink.com file from my development sources with this 
compiler.  The command line options seem to work, but I couldn't get 
transfers going when I made a quick test.

Using RS-232 at 38400 bps on MS-DOS requires at least some direct 
hardware access, as the BIOS INT 14h doesn't go beyond 9600 bps.  I 
found excellent sample code at the same site where I found a version of 
bcc that is accompanied with a primitive C library for MS-DOS: 
<URL:http://www.cix.co.uk/~mayday/>.  The file talk.zip contains a fast 
terminal program with source code.  If someone is interested in making a 
decent MS-DOS port of cbmlink, this site is a good starting point.

Please contact me if you're interested in finishing this port.  I'm not 
that interested myself, as I don't have any 8086-class hardware, but 
some of you might still have old 8086 or 80286 boxes lying around, 
waiting to be networked with Commodore computers.
