linksys wireless pcmcia card

Per QNX web site I inserted the following into the net.cfg file defining
PCCARD_VEND_LINKSYS device using the orinoco dll. System starts-up w/o
error, card is found using pin but network not accessible. Wireless
requires that I state the name of the network (specific ESSID) that I am
joining. I am not sure how or where to indicate this for QNX.

Any help would be appreciated.
