Fair point.  What I meant (or at least, with hindsight, what I meant to mean!) 
is that while it's true that LiveCode "has no USB support" the original poster 
might well find that LiveCode on a modern machine with no RS232 port can 
operate a USB modem in exactly the same way as HyperCard was able to operate 
an RS232 modem on the hardware of that time.

LiveCode has no USB support, and for example I don't expect that it would be 
easy to control an arbitrary USB-connected device in the absence of a driver 
for it.  But responding to

I would strongly suspect that a USB modem would be sold with a driver, and 
that a LiveCode stack running on a machine on which the driver has been 
successfully installed would be able to control it using the open 
driver/serialControlString etc elements of the language.
