Hi, I know that I can do this, but for the life of me I can't figure out how. How do I identify a give filename as a name used by a device driver. i.e. lpt1, com1 and the sorts?

Wildside ... 2nd regeneration of a Time Lord Open the file using DOS function 0x3d then use function 0x44 subfunction 0x00. The return will tell you if it's a file or a device. If a device, there's some more bits to tell you if it's stdin, stdout, etc. Ed ekalenda@cup.portal.com
