24S-registersS8 (pause time for comma; range = 0–255)A comma included in the dialing sequence is interpreted as a delay. The defaultdelay time is two seconds.S12 (escape code guard time; range = 0–255)The guard time aids in recognition of the escape sequence, useful since differentnumbers of escape characters mean different things. For example, one Escapecharacter is not recognized as a pause until the guard timer expires, indicating noother Escape characters were entered as part of the Escape sequence.This holds the value of the guard time in milliseconds. The value of each digit is 20milliseconds. The default value is 50 (one second).S52, S53, S54 (product code response)These registers contain the Product Identification code and will output a three digitcode in response to the “ATI0” command.Default value is “960” (Smartmodem V-series 9600 modem). Other possiblevalues are: “122” (Smartmodem 1200) and “240” (Smartmodem 2400). Theseregisters will not be altered by software reset.S66 (AT/KBD autobaud interpretation; range = 0, 1)A value of zero (0) means only Hayes autobaud is possible. A value of one (1)means both Hayes and keyboard dialing autobaud is allowed.S51 (delay until modem pool activation; range = 0–255)Each increment of S51 represents a 0.25 second delay before outbound modempool activation. Default is 16 (4 seconds). This register will not be altered bysoftware reset.
