Serial download

This is not the preferred method, but we've documented it here in case you need to use it.
This procedure requires that you first connect your Dual Link unit to a Com port on your
PC using a DB-9 to DB-9 cable.
Once this is done, click Start>Programs>3Com Dual Link Modem>Advanced>Serial
