Just as a comment, I don't normally use FreeDOS but if this test doesn't work it's a serious problem -- not just testing for the existence of drive letters. All the standard character devices in DOS (NUL, CON, COMx, LPTx, CLOCK$, etc.) are supposed to act like there is a file by that name in EVERY subdirectory on every disk there is. This means you can't (or at least shouldn't be able to) create a file with any of those device names anywhere and also allows input/output redirection using those devices from anywhere. I've never experimented with "non-standard" character devices (something normally installed with a device driver in CONFIG.SYS) but suspect they would (or at least should) work the same way. _______________________________________________ Freedos-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-devel
