The information in this document applies to:
WordPerfect® 6.0 for DOS

Problem

Symptoms: While using a PCMCIA Modem and WordPerfect's fax capabilities, it is difficult to achieve 520K of free conventional memory (WordPerfect 6.x requires 520K of conventional memory for its Fax Services). Solutions: Because of the resources the PCMCIA Modems requires, conventional and upper memory will be very limited. These modems are better suited for the Windows opperating system since it is less sensitive to the lack of conventional memory.

The only way to free up enough memory for WordPerfect 6.x for DOS will be to eliminate ALL of the unnecesary TSRs and Device Drivers from the users AUTOEXEC.BAT and CONFIG.SYS files.

Note: The user's PCMCIA Modem Drivers and the WorPerfect Fax Drivers (FAXDIR.EXE and FAXB.COM) must still load. Causes: PCMCIA Modems are not automatically recognized by the computer until a number of card services drivers load into memory. Without the card services drivers, the modem's COM Port won't even be physically recognized on the computer. Additionally, the card services drivers usually require a large section of upper memory so they place an exclude statement on the user's EMM386.EXE command line in the CONFIG.SYS file.

The effect of this is that not only does the user have to load additional programs and drivers, they also have less upper memory to use to free up conventional memory. The WordPerfect 6.x Fax Drivers (FAXDIR.EXE and FAXB.COM) will require as much as 90K of memory. To fax properly, WordPerfect 6.x for DOS recommends a minimum of at least 520K free.
