1.5.6.2 Hayes Register
Set
In addition to the commands, there are a group of registers for which data is entered in the following
format: AT{register}={value}<CR>. The following Hayes registers are supported:
S0
- Number of rings on which to auto-answer
S37
- Maximum rate adaption speed
%A2
- B-channel protocol
%E8
- V.120 MFO mode selection
!C4
- B1-channel configuration
!C5
- B2-channel configuration
!C6
- Multiple Subscriber Numbering
!C7
- TEI selection
!C8
- ISDN Line Failure Detection enable/disable
The following is a more detailed description of the Hayes registers listed above:
S0 (Rings on Which to Auto-answer a Data Call)
Range
Default
0 to 255
0
Description
If set to 0 auto-answering will be disabled.
Any other value will cause one ‘RING’ result code to
be sent to the DTE after which the call is answered.
S37 (Maximum Rate Adaption Speed)
This forces the baud rate when handling incoming calls, to that defined by the S37 register contents,
provided auto-answer is set. Once a call is terminated the baud rate remains that set by the S37
register.
Value
Rate (baud)
0 (default)
Same as last AT speed
9
9600
12
19200
13
38400
18
57600
31
115200
%A2 (CSD Protocol)
Selects the protocol to be used for the circuit switched data calls. Note that %A2 cannot be changed
while a B-channel call is active.
Value
Description
2 (default)
V.120 Rate Adaption on B-channel.
3
Voice Calls.
15
PPP.
20
Transparent protocol.
1.5.6.2.1 V.120 Parameters
%E8 (Multiple Frame Operation Mode Selection)
In Multiple Frame Operation (MFO) mode, frames are acknowledged and retransmitted if errors occur.
Value
Description
0
MFO mode on.
1(default)
MFO mode off.
