Subject: Serial card help

Is anyone here familiar with the Jade S-100 serial/parallel card? I've just
fixed my brand new S-100 system after 2 months of work, and I've managed to get
everything working; except the serial card. This is VERY frustrating, seeing as
when I boot my system, I see CPM v. 1.4 etc... on my video screen, and I can't
do anything else except stare at it because I can't type anything! I have no
idea what the problem is, I've detected pulses at the serial input whenever I 
press a key; however, the DATA AVAILABLE line stays high, and RECIEVE DATA
AVAILABLE' won't go low to reset DAV...Another thing is, I wrote a simple test
program to output a stream of A's to the port, along with the control port 
data. Because I used a simple loop(I'm not too famailiar w/ Z80 m/l.), the 
control data is continuously outputted to the port. However, I can't detect a 
pulse on CONTROL STROBE', meaning that it is not getting the data. The only
cause that I can think of is that I have the port address set wrong. However,
I've checked, double checked, and rechecked the port switches, and they are 
set right.

If anyone can help me on this, I will TRULY appreciate it. It's very 
frustrating to get 10 S-100 cards working, and be stuck on one little serial
card...
