SYMPTOMS

When you use the AT command at the MS-DOS Command Prompt and enter a path statement greater than 127 characters, the following error message appears:

The command line exceeded 259 characters.
Invalid command.

Next, the correct syntax for the AT command appears.

NOTE: Additional switches do not affect the 127 character path limit.

WORKAROUND

To work around this problem, make sure that the path statement is less than 128 characters.
