LT Win Modem

The LT Win Modem has shipped out with several new PCs on the market. Since it does not have an EPROM chip on the modem, it is a generic "software" modem that requires specific drivers for best performance. An EPROM chip is a memory chip allowing "flash" V.90 upgrade utilities to write to the modem directly. The LT Win Modem, instead, only uses drivers which can sometimes be difficult to install. Additionally, certain versions may work best for certain phone lines but perform worse for others. It is not uncommon to try several versions before finding one that works best for your situation. WITH THE RIGHT DRIVERS, THE LT WIN MODEM CAN BE A GOOD MODEM.

Because the LT Win Modem is generic, it is also known by several other names:
