[DSP-10] Testing KDSP10/DSPx

[Benjamin E Lamb]

Windows XP does not support a serial ports!  The WinXP API is NOT
backward compatible
with DOS or Win95, Win3.x.  Microsoft has declared the serial
port to be obsolete.  Serial to USB adaptors also are useless.
Not even PCMCIA adaptors will work with DOS programs under 
WinXP.  We have been had. Gentleman.
