4.21Squelch Delay (AT S168)
Note: engineering function only.
This command changes the delay between the Squelch being received and the FX929 modem IC looking for preamble in the receive audio. This allows the modem to be used with different transceivers. The command format is as follows:
| AT S168=n<CR><LF> |
Where: | n = 1 - 255 (ms) |
Default: | n = 10 |
Read | AT S168?<CR><LF> |
Read Return: | nnn<CR><LF> |
Example: | AT S168=10<CR><LF> 10ms delay between squelch |
| and preamble |
4.22Enable/Disable Receive Output Data (AT &D) This command disables output of any received data.
Note that the CD output continues to operate when the data output is disabled. The command is of the format:
| AT &D=n<CR><LF> |
|
Where: | n=0 disable output |
|
| n=1 enable output |
|
Default: | n=1 (enabled) |
|
Read: | AT &D?<CR><LF> |
|
Read Return: | n<CR><LF> |
|
Example: | AT &D=1<CR><LF> | enables receiver data output |
4.23Enable/Disable Input Echo Data (AT &E)
This command enables/disables input echo on the screen. The command is of the format:
| AT &E=n<CR><LF> |
|
Where: | n=0 disable echo |
|
| n=1 enable echo |
|
Default: | n=1 (enabled) |
|
Read: | AT &E?<CR><LF> |
|
Read Return: | n<CR><LF> |
|
Example: | AT &E=1<CR><LF> | enables echo input |
