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.

OK  Appears when the value is supported.

ERROR  Appears when the selected value is not recognized or is not 
supported.

The CTS Operation Command 

&Rvalue

sets the operation of the CTS pin. The following table shows the 
allowable values. These values are overridden by the ßow control 
selection if hardware ßow control (RTS/CTS) is selected.

OK  Appears when the value is supported.

ERROR  Appears when the selected value is not recognized or is not 
supported.
