S-Registers
This section describes the S-Registers supported by the MultiAccess modems.
S0
Auto Answer
Compatibility: Superficial. Default: 1 Min: 0 Max: 255
In standalone modems, S0 is the number of ring cycles before automatic answer and, if zero, disables
automatic answer. In the MultiAccess, upon the onset of ringing, the modem will not act until the "A" (answer)
command is received from the User specific application. Traditional auto answer is not supported.
S2
Escape Character
Default: 43 '+' Min: 0 Max: 127
This register defines the escape code character. The default character is the plus (+) sign (decimal 43). It may
be set to any ASCII character, refer to the ASCII Conversion Chart at the end of this appendix. Setting a value
greater than 127 results in no escape character, and therefore no means of entering command
on-line mode without breaking the on-line connection.
S3
Carriage Return Character
Default: 13 '\r' (CTRL-M) Min:0 Max 127
This register defines the character recognized as the Carriage Return (Enter or Return Key). This register may
be set to any ASCII character, refer to the ASCII Conversion Chart at the end of this appendix.
S4

This register defines the character recognized as Line Feed. S4 may be set to any ASCII charater, refer to the
ASCII Conversion Chart at the end of this appendix.
S5

the ASCII Conversion Chart at the end of this appendix.
S7
