Not for what I need to do.  I need the Boot module to know what Disk 
BASIC had set the 6551 for (the command and control registers).  It 
knows this on a first time boot because the data is there on the 
chip.  Hitting reset clears the registers.  Boot then can't read 
os9boot from the virtual disk across the serial link unless it sets 
the 6551 back up.  I could take a lazy approach and just set the baud 
rate to say, 115200 bps, but what if the user wants only a 19200 bps 
connection, or even a 9600 bps.
