V.34 technology enables both modems to transmit data at 33,600 bps and achieve throughput rates to 300,000 bps with V.42bis and MNP 5 data compression. The Parallel Port Solution Microcom is the first modem manufacturer to offer the parallel port interface solution.
Users can choose either serial or parallel port operation with minimal set up.
The parallel port interface optimizes the performance of Windows communications applications, where most PC serial ports are limited to throughput rates of 19,200 bps. These PCs can be upgraded to the 16550 UART to support throughputs of 38,400 bps. But to deliver true V.34 throughput, PCs must be retrofitted with high-speed accelerator cards. Therefore, most V.34 modems on the market today have a hidden cost associated with high speeds. Microcom's parallel port drivers reroute the data stream through the PC's high-speed parallel port.
