For a multi port serial card that supports 5 bit code try the Lava Quarto
PCI or 4 port serial PCI card. It can be hard to locate but is cheaper
then many of the other 4 port cards. Also, it comes with a life time
warranty which they honored for me after a lightening hit. For more info
check out www.lavalink.com.
