To run a client of the Ironclad app, do the following.
First, in an administrative command prompt, create an ARP entry for the machine's Ethernet address by running this command with appropriate concrete values substituted:
arp -s 10.1.2.3 90-e2-ba-4f-0c-5b
Next, start a serial port connection by running the following from cygwin:
plink -sercfg 115200,8,n,1 -serial com3
Next, start the boot server and reboot the Ironclad server machine.
