- This is a quick reference guide for commands and codes
- ======================================================
-
- COMMANDS: AT Attention code, precedes all commands
-
- A Answer call without waiting for ring
- A/ Repeat last command line, replaces AT
- and no carriage return required
- Cn n=0 Transmitter off
- n=1 Transmitter on (default)
- Ds Dial a number
- s=0..9 # * T P R , ;
- T = touchtone P = pulse dial
- R = reverse mode "originate only"
- , = pause
- ; = return to command state after dial
- En n=0 Do not echo chrs in command state
- n=1 Echo back all chrs in command state
- Fn n=0 Half-duplex
- n=1 Full-duplex (default)
- Hn n=0 On hook (hang up)
- n=1 Off hook
- n=2 special off hook
- In n=0 Request product code
- n=1 Request check sum
- Mn n=0 Speaker always off
- n=1 Speaker on until carrier (default)
- n=2 Speaker always on
- O Return to on-line state
- P Pulse dial
- Qn n=0 Result codes sent
- n=1 Result codes not sent (quiet)
- R Reverse mode "originate only"
- Sr=n Sets register "r" to value "n"
- Sr? Reads contents of register "r" as
- a decimal number 0 - 255
- T Touchtone dial
- Vn n=0 Result codes sent as digits
- n=1 Result codes sent (verbal words)
- Xn n=0 Basic result codes 0 - 4
- n=1 Extended codes 0 - 5
- Z Software reset to default values
