terminal window when you type, the modem’s echo setting is probably set to off. In this case, issue the ATE1 command.
∙When a command is successfully issued and accepted, a modem responds with a “Result Code.” Your modem supports both “verbose” result codes (i.e. “OK”), and “numerical” result codes (i.e. “0"). You can use the ATV command to set it one way or the other as follows:
Command
Description
ATV0 | Select numerical result code. |
ATV1 | Select verbose result code. |
There are a few basic commands that do not require the “AT” command prefix. These are as follows.
Command | Description |
A/ | Repeats the last issued AT command once. |
A> | Repeats the last issued AT command once, or |
| |
| until a key is pressed or a connection is made. |
<any key> | Terminates the current connection attempt, if |
| pressed while modem is handshaking. |
+++Escape code sequence. Entered while the modem is in Data Mode. Returns modem to Command Mode.
Your modem supports several groups of AT commands:
AT Command Set/Type | Example |
Basic AT (Hayes compatible) | ATB0 |
Basic AT$ (on line help) | AT$ |
Extended AT& commands | AT&N0 |
Extended AT* commands | AT*I1 |
Fax AT+ commands | AT+FCLASS=2 |
