[plt-scheme] serial port settings

Although we use it continuously, I haven't recently looked at that  
stuff.  Tonight I might have time to dig it up and make a clean  
example.  I merely read POSIX serial tutorials available on the web,  
wrote a C program that tested from the command line, then used the  
PLT docs to develop an extension.  That was several years ago, using  
the FFI might make more sense now (maybe even then, too).

More details: I used a Keyspan USB-to-serial adapter ($35) on OS X;  
it dutifully puts a standard serial driver in /dev.  All of the  
standard serial driver commands that I need (ie baud, control  
signals) work fine.  I don't know what the Windows developer had to  
change for that port, but it wasn't much.
