\Kn

5

Set break control

 

In Connect State, if reliable mode then transmit break to remote:

 

 

n = 0,2,4

Enter command state, but do not send a break.

 

 

n = 1

Destructive/expedited

 

 

n = 3

Non-destructive/expedited

 

 

n = 5

Non-destructive/non-expedited

 

In Command State, if reliable mode then transmit break to remote:

 

 

n = 0,1

Destructive/expedited

 

 

n = 2,3

Non-destructive/expedited

 

 

n = 4,5

Non-destructive/non-expedited

 

In Connect State, if direct mode then receive break at serial port:

 

 

n = 0,2,4

Immediately send break and enter command state.

 

 

n = 1,3,5

Immediately send break through

 

In Connect State, receive break at modem port, send to serial port:

 

 

n = 0,1

Destructive/expedited

 

 

n = 2,3

Non-destructive/expedited

 

 

n = 4,5

Non-destructive/non-expedited

\Nn

Set Operating Mode: Determines the type of

connection attempted by the modem.

 

n = 0 Normal Mode-No data compression or error correction, but uses speed buffering.

 

n = 1

Direct Mode- No data compression, error correction, or speed buffering.

 

n = 2

MNP Reliable Mode-The modem attempts to negotiate an MNP error-correction 'reliable' link, hanging up if it fails.

 

n = 3

V.42 Auto-reliable Mode * If V.42 detection is enabled (-Jn), a LAPM or MNP link can be detected and negotiated, otherwise only LAPM will be

 

 

attempted. If configured for -J0 and a protocol connection is not made, the modem will hang up. If configured for -J1 and a protocol

 

 

connection is not made, the modem will fall back to speed buffering mode.

 

n = 4

V.42 Reliable - The modem attempts to negotiate LAPM error correction, hanging up if it fails.

NOTE: 300 bps does not support synchronous operation. The mode will automatically fall back to MNP asynchronous operation.

\O

none

\X

0*

Processes flow control characters *

 

1

Processes flow control characters and passes them through to the local or remote so they can process the characters.

\Y

none

Switch to reliable mode

\Z

none

Switch to normal mode

-Jn

0

Disable the V.42 detect phase

 

 

(\N3,\N4 operating mode)
