| 1. Issue AT &Q(0,5-9) &W from a Synchronous Terminal |
| to restore the modem to Asynchronous Mode. |
| |
| 2. Connect modem to an Asynchronous Terminal with the |
| DTR signal (line 20) disabled (a "break-out" box |
| works very nicely for this) and issue the |
| configuration you want or AT &Q(0,5-9) &W to return |
| the modem to Asynchronous Mode. |
