Random thoughts ....
Did you load a driver for the USB/serial converter?
Is there another serial device that you could try it with?
Another cable?
The "Cat" on the 990 display will blink if they're talking to each 
other. If it blinks, but doesn't do the right thing, serial port parms 
are most likely wrong.
Does the USB cable show in Device manager as a serial (com) port? Or 
whatever the Mac equivalent is?
Are the serial parameters correct? 4800 baud, 1 start bit, 8 data bits, 
no parity, 2 stop bits.
