Configuring DTR and DSR Signals
Configuring DTR and DSR SignalsIntroduction
This section describes how to configure DTR and DSR signals for those access servers that do not support the other modem signals. DSR flow control must be disabled when you are using the various port characteristics to control the DSR and DTR signals. DSR flow control can override the port characteristics.
Port Characteristic Effects on the DTR and DSR SignalsThe following table shows the enabled port characteristic effect on DTR and DSR signals:
Enabled Characteristic | DTR and DSR Actions |
|
|
SIGNAL CONTROL | DTR is deasserted for 5 seconds as a |
| consequence of a logout; otherwise, it is |
| always asserted. |
(SIGNAL CHECK and | Solicited remote connection is established |
DTRWAIT disabled) | regardless of the state of DSR. Reception of |
| asynchronous data is accepted once the |
| connection is established. |
| Port is logged out if DSR is deasserted after |
| initial assertion. |
|
|
DSRLOGOUT | DTR is always asserted. |
(SIGNAL CONTROL and | Solicited remote connection is accepted |
SIGNAL CHECK disabled | regardless of the state of DSR. |
| Port is logged out if DSR is deasserted after |
| initial assertion. |
| Reception of asynchronous data is not be |
| accepted unless DSR is asserted. |
|
|
SIGNAL CHECK | DTR is always asserted. |
(SIGNAL CONTROL | Solicited remote connection will not be |
disabled) | accepted unless DSR is asserted. |
| Port is logged out if DSR is deasserted after |
| initial assertion. |
