SYMPTOMS

In Windows 95, using the COPY FILE command to copy a file to LPT1 causes the "Invalid Seek Offset" error in Visual FoxPro 5.0 and 3.0b if the port is not captured. If the port is captured, the error "Invalid Path or File Name" appears. However, in Windows NT 3.51 and Windows NT 4.0, using the COPY FILE command to copy a file to LPT1 first returns a warning message that the file will be overwritten unless SAFETY is set to OFF, then the message "Error Writing to File" appears.

RESOLUTION

To work around this problem, do the following:

COPY FILE filename TO LPT1.DOS

COPY FILE Test.txt TO LPT1:

Under Windows 95, you get an "Invalid Seek Offset" error message dialog box when the port is not captured. If it is captured, the error "Invalid Path or File Name" appears.
