Remote possibilities: not in your office? remote control software make it simple to access your computer

Entrepreneur, Nov, 1997 by Cassandra Cavanah

These programs share the same basic functionality. Their main purpose is to give users an easy way to access a remote computer and use it as if you were actually sitting in front of it. After dialing into the computer via modem (these programs also let you connect to computers via the Internet), you can open programs and files, make changes to them, save them, move them and more. Iran employee is sitting at the computer you're accessing, you can chat with him or her in real time.

The other important function shared by these programs is something called "file transfer." If you use two computers - one at home and one in the office, for example - you're probably aware of the wide array of problems that can arise when you've worked on a file in two places. For example, you may leave an important file behind or unknowingly access an older version of a file. By using a program with file transfer capabilities, you can do more than simply copy files from one machine to another (a process that can lead to errors when the wrong file is copied over the right file). Instead, a file transfer program manages the process, making it easy for users to see what files are being transferred to and from each machine. As notebook computers become more and more popular traveling companions for businesspeople, file transfer is becoming increasingly important. In fact, Microsoft includes Briefcase, its own file transfer program, with Windows 95.

* ON THE ROAD AGAIN

Since its DOS days, Traveling Software's LapLink for Windows 95 has long been the favorite among laptop users looking for a quick and easy way to synchronize files between two machines. With this version of LapLink, Traveling Software had improved on its file synchronization capabilities by adding Xchange Agent for scheduling automatic file transfers and improving file transfer speeds. LapLink's SpeedSync feature also helps speed up the file transfer process by comparing files on your two machines and transferring only the changes that have been made since the last connection. If the connection between your computers fails while performing a file transfer, LapLink will send only the missing portion of the file upon reconnect.

There are numerous ways users can achieve a connection between two computers. In addition to basic parallel port and direct dial-up connections, users can also perform remote control and file transfer functions via the Internet (both machines must be logged on) or by dialing into a company's local area network (LAN). LapLink incorporates data encryption for safe and secure remote sessions. Once connected to another PC - either via modem, direct cable access or a network connection - users can access its contents and peripherals as if they were sitting in front of it. Additionally, because LapLink is very laptop-oriented, users can easily set it up to support a wireless connection using infrared ports.

To get users through these processes, LapLink includes a Quick Step dialog box. This help program walks you through the steps of making a connection and performing a file transfer. The LapLink interface isn't exactly intuitive - menu icons are unmarked and their functions are not very obvious - so Quick Steps are a must.

* ANY TIME, ANYWHERE

Symantec sent me an early release of pcANYWHERE32 8.0, a 32-bit version of the company's extremely popular remote control program, for review. The program comes with support for all major operating systems, including Windows 95, Windows NT, Windows 3.1 and DOS. It installed quickly and easily on my Windows 95 system.

This program's extremely advanced functions are hidden under a simple-to-operate interface. Where LapLink lacks intuitiveness, pcANYWHERE has plenty. Its icons are clearly marked (for example, "Be a Host PC," "Remote Control," "File Transfer" and so on), and once you click on the icon, each process is easy to follow. For first-time users, there's an icon marked "Quick Start" for setting up a variety of connections. Once the connections are created, icons reside within pcANYWHERE for one-click connections - whether you're accessing the remote computer via parallel port, modem, Internet connection or LAN.

If your office uses a Windows NT server, pcANYWHERE, with its enhanced Windows NT integration, may be the right choice for your organization. For example, this program integrates with Windows NT to monitor remote control access. The program also lets users perform multiple remote sessions from a single PC using various devices, such as a modem, a LAN connection or a parallel port.

Symantec's pcANYWHERE comes with plenty of bells and whistles, including a video-chat function that lets users videoconference from within the program. This technology allows up to 256 users to view a presentation or demo. There are also four levels of encryption security built into the program so users need not worry about sending sensitive data across phone lines.

* COPY THAT

Microcom's Carbon Copy 32, like Symantec's pcANYWHERE, comes with a parallel port cable for direct PC-to-PC connections. This product was easy to install - it comes on just two floppy disks - and was relatively easy to set up, though I found the other two products more intuitive. Carbon Copy is the runner-up in this category and has done an admirable job keeping up with the two leaders. This 32-bit version incorporates all the functions offered by the other two programs, including a Windows 95-like interface and Long File Name support. It also has extensive file transfer capabilities, including the ability to resume a transfer where it was cut off in case of a lost connection and the ability to automatically disconnect after a transfer is completed. It will also transfer only the changes to a file instead of an entire file. Its remote control functions are similar to the other products reviewed here: There's support for multiple users, voice and data chat, Internet connections, and much, much more.
