APPENDIX A
| 1 | Enable Bps rate adjusting | |
\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 | |
|
| n = 5 | |
| In Command State, if reliable mode then transmit break to remote: | ||
|
| n = 0,1 | Destructive/expedited |
|
| n = 2,3 | |
|
| n = 4,5 | |
| 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 | |
|
| n = 4,5 |
\Nn | Set Operating Mode: Determines the type of | connection attempted by the modem. | |
| n = 0 Normal | ||
| n = 1 | Direct Mode- No data compression, error correction, or speed buffering. | |
| n = 2 | MNP Reliable | |
| n = 3 | V.42 | |
|
| attempted. If configured for | |
|
| 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 | Originate reliable link |
\Qn | 0 | Disables flow control |
| 1 | XON/XOFF software flow control |
| 2 | Unidirectional hardware flow control |
| 3* | Bidirectional hardware flow control |
\T | 0* | Disable inactivity timer |
|
| |
\U | none | Accept reliable link |
\Vn | 0 | Enables codes defined by ATV command |
| 1 | Enables modified MNP codes |
| 2* | Enables extended V.42 codes |
\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 |
0 | Disable the V.42 detect phase | |
|
| (\N3,\N4 operating mode) |
| 1* | Enable the V.42 detect phase |
