No.  All vmodem does is create a virtual modem between your comm 
program and the network.  It will respond to modem commands from 
the terminal program with modem-like responses; eg "AT" will 
return an "OK" etc. If you tell vmodem to "dial" (ATDT) an 
internet domain address, vmodem will parse the address out of the
command and pass it along to be resolved into an ip address and
if/when the remote site accepts the connection, vmodem will pass
the appropriate modem-like "CONNECT" response back to the
terminal program.  As far as the terminal program is concerned it
may as well be talking to a real modem.  It doesn't matter at all
whether you have a permanent or intermittent connection to the
internet, although people running BBS's find vmodem particularly
handy because it allows their serial-modem based BBS software to
transparently work over a tcp/ip network connection.  But it
works just as well from the client side.
