I have two P4 PCs (one running XP HM and other XP pro) connected
through a switch on ethernet. One is mine and other belongs to my 13 year
old son. Both the systems have their own dial-up modems but we share the
same phone line. Majority of the times there is no problem with telephone
line sharing but sometimes he has to abort so that I can go online or vice-versa.
Is it possible to share a modem at "will" i.e. only when it is already being used?
The thing is, majority of the time, other PC will be off and so making one of the
modem primary is not a good option.
