What is so hard about hardware?

Article Abstract:

Extended Systems' Jeteye ESI-9860 infrared transceiver ships with no software, making it virtually useless, while Traveling Software's Laplink for Windows 95 remote access software has some significant flaws. Extended Systems claims it now ships software with the Jeteye, which is designed to let computers exchange data via infrared ports. Microsoft offers free infrared drivers for Windows 95 on the company Web page, and this software works well, although installation is difficult and the online manual does not help. Laplink does not work well with the Windows 95 infrared drivers, making the ports lose connections even when they had not been moved. Laplink occasionally finds it difficult to sustain modem communications and is subject to crashing. The 32-bit version of Laplink cannot install itself remotely on other machines as its predecessors could, and it automatically saves the latest version of a file, instead of allowing users to preserve the version they choose.

Of communications a la modem

Article Abstract:

Modems have generally become commodity items, but there are some distinct differences that affect their ability to move data and maintain connections. Owners of basic 14.4-Kbps modems often assume that upgrading to 28.8-Kbps modems will double the speed of their connections. However, phone lines are often too noisy to permit full-speed connections, and a modem cannot eliminate bottlenecks on the server or the Internet. The only communication protocols that truly matter are V.32 and V.34, which are the worldwide standards promulgated by the International Telecommunication Union. Other standards, such as the V.FC, are only useful when communicating with modems that have the same standard. Digital Simultaneous Voice and Data (DSVD), a standard that allows simultaneous data and voice communications, has not yet been finalized and may end up being useful only in special situations.

A user challenge: getting new modems up to speed

Article Abstract:

The new V.90 standard for 56K modems eventually will simplify the technology, but shoppers still must ensure compatibility with an Internet provider's service. This single international standard, announced by the International Telecommunication Union agency in Feb 1998, is expected to complete the formal approval process in Sep 1998. The two current but separate modems consist of 3Com's X2 and Rockwell International's and Lucent's K56flex. Rockwell, Lucent Technologies and 3Com recently announced V.90-based modem intercompatibility among their server hardware. 3Com started another industry trend by offering free software that would upgrade many of its X2 modems to V.90. Some users are experiencing difficulties after upgrading their modems, however.
