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.
All three products' features are truly comparable. They all offer fast remote transfer speeds by letting users adjust the amount of graphics that are being transmitted. Similarly, file transfer capabilities have become streamlined in all three products so users are able to perform this maintenance function as quickly and painlessly as possible. Additionally, all three products offer multiple, simultaneous connections between numerous users, though Carbon Copy's and PCANYWHERE's support for 256 users beats out LapLink's ability to support just 11 users. They also all support various types of connections, though I found both LapLink and PCANYWHERE easier programs to set up. If you're torn between these products, check out their Web sites and download trial versions. You can test them and see which one works best for you.
