CTA 500 dm On Line Guide P0873832 Issue 05
All modes of operation may not apply with all selections of rate
adaptation protocols.
When &D is set to 3, assertion of the DTR signal causes a software
reset of the CTA 500dm, even if it is already in the command state.
If the CTA 500dm detects that it has been enumerated by a
Windows95 Plug and Play software driver, the &D3 reset takes
place only when the CTA 500dm is in one of the on-line states.
Otherwise, the assertion of DTR indicates the possible request for
the Windows95 Plug and Play identiÞcation string.
