ECC Commands (Continued)
Command | (Conexant) |
|
|
+ER: a | Select error control protocol: NONE=error control not in use, |
| LAPM=V.42 LAPM protocol, ALT=MNP. |
|
|
+ER=n | Error control reporting: 0=disable, 1=enable. |
|
|
+ES=a,b,c | Select error control and synchronous mode (b and c are |
| optional). |
| ■ a is requested mode when modem is originator: 0=initiate |
| call with direct mode, 1=initiate call with normal mode, |
| 2=initiate V.42 without detection phase, 3=initiate V.42 with |
| detection phase (default), 4=initiate MNP, 6=initiate V.80 |
| synchronous access mode when connection is completed. |
| ■ b specifies fallback mode when modem is originator: |
| 0=LAPM, MNP, or normal mode error control optional |
| (default); 1=LAPM, MNP, or direct mode error control |
| optional; 2=LAPM or MNP error control required; 3=LAPM |
| error control required; 4=MNP error control required. |
| ■ c specifies fallback mode when modem is answerer or |
| specifies V.80 synchronous access mode: 1=error control |
| disabled, use normal mode; 2=LAPM, MNP, or normal |
| mode error control optional (default); 3=LAPM, MNP, or |
| direct mode error control optional; 4=LAPM or MNP error |
| control required; 5=LAPM error control required; 6=MNP |
| error control required; 8=initiate V.80 synchronous access |
| mode when connection complete. |
|
|
+ESR=0 | Disable selective repeat option in V.42. |
|
|
+ETBM=a, | Handle data remaining in modem buffers on call termination |
b,c | (b and c are optional): |
| ■ a=0 disconnect occurs immediately and buffered transmit |
| data is discarded. |
| ■ b=0 disconnect occurs immediately and buffered receive |
| data is discarded. |
| ■ c=0 modem does not attempt to deliver buffered data and |
| discards data. |
