Certain Command Mode configurations are stored in memory registers called,
S0
Number of Rings Until Modem Answers
Unit: | 1 ring |
Range: | |
Default: | 1 |
Description: | S0 defines the number of rings the modem waits before answering an incoming call. |
| The default value is one ring (Decimal 1), which means that the modem answers the |
| call immediately after the first ring. The maximum number of rings that can be |
| configured is 255. Setting the value to zero (0) disables |
S1
Rings Which Have Occurred
Unit: | 1 ring |
Range: | |
Default: | 0 |
Description: | S1 counts the number of rings that have occurred. It is a “read” type of register and |
| is seldom, if ever, used in typical operation. Each time an incoming ring signal is |
| detected, S1 increases its value by one, up to a maximum of 255. If you set S1 to a |
| value other than its default value of zero, or if the value is increasing with rings, this |
| new value remains stored in S1 for eight seconds after the last ring is counted, after |
| which time the value reverts to zero. |
S2
Escape Code Character
Unit: | ASCII Character |
Range: | |
Default: | 43 (+) |
Description: | S2 defines the escape code character. The default character is the plus (+) sign |
| (Decimal 43), but may be set for any ASCII character. Setting an S2 value greater |
| than 127 results in no escape character, and therefore no means of entering |
| Command mode from |
S3
Return Character
Unit: | ASCII Character |
Range: | |
Default: | 13 (^M) |
Description: | S3 defines the character recognized as Carriage Return (RETURN) or “Enter”. S3 |
| may be set for any ASCII character. |
