Racal-Vadic has announced their new VA4400 line of modems. The new modem incorporates a 2400-bps, full duplex modem, a VA3400, a Bell 212A and a Bell 103 in one unit. The VA4401 can originate calls to, and answer calls from, all four of these modem types. It is build around the 16-bit Fairchild 9445 microprocessor, which performs the analog signal processing functions for all four modems. It automatically determines if the modem it is communicating with is 2400 bps, 1200 bps or 300 bps and operates at the highest speed. It can be connected to the VA811 autodialer and/or direct connected to phone lines. The VA4401 will sell for around $1945, in single quantities. It will also be available in a 2400 bps version only for $1745. geoff
