Irving,
  I have a cheap way to have another RS232 port on the M100. All you have to do
is hook up another HD6402 uart chip to the printer port ! The chip is a $5.00
item. As for the relays, they can be replaced with a TIP120 darlington
transistor , Radio Shack has them for around $2.00 apiece. If you want more
info, leave me a message here or better yet call me at 302-695-2047 between
9:00 am and 5:00 pm EST.
