97EOD is determined by two sequential EOF marks with no data between. 98There are old systems which typically wrote three EOF's between tape 99files. 100.Xr tcopy 1 101will erroneously stop copying early in this case. | 99EOD is determined by two sequential EOF marks with no data between. 100There are old systems which typically wrote three EOF's between tape 101files. 102.Xr tcopy 1 103will erroneously stop copying early in this case. |
