Not necessarily. We have a product that uses RS232 as a configuration and
data collection port. We have a consderable investment in Palm OS software
to do this configuration and data collection, but more and more Palm OS
devices are being shipped with no RS232 available, instead using USB. We
can't use USB to RS232 converters, because the Palm is a USB peripheral,
not a USB controller. The FTDI chip is absolutely useless in this
scenario. I'm still not sure what we will do when the serial ports on
Palms finally go away.
