DIP SWITCHES**************************************************** * Factory Switch Setting Function ------------------------------------------------------------ - 1 UP Data Terminal Ready (DTR) Operations UP Normal DTR operations: computer or terminal must provide DTR signal for modem to accept commands; dropping DTR terminates a call DOWN DTR always ON (Override) 2 UP Verbal/Numeric Result Codes UP Verbal (word) results DOWN Numeric results 3 DOWN Result Code Display UP Results suppressed (Quiet mode) DOWN Results enabled 4 UP Command Mode Local Echo UP Keyboard commands displayed DOWN Display of commands suppressed 5 DOWN Auto Answer UP Modem answers on first ring DOWN Auto answer suppressed 6 UP Carrier Detect (CD) Operations UP Modem sends CD signal when it connects with another modem, drops CD on disconnect DOWN CD always ON (Override) 7 UP Power-on and ATZ Reset Defaults UP Load NVRAM defaults DOWN Load factory (ROM) defaults 8 DOWN "AT" Command Set Recognition UP Recognition disabled (Dumb Mode) DOWN Recognition enabled (Smart Mode) S- REGISTERS*************************************************** ***** Register* Default Function ------------------------------------------------------------ ------ S0 See DIP Sets the number of rings on which Switch 5 to answer in Auto Answer mode. When DIP switch 5 is UP, the modem answers on the first ring; S0=1 has the same effect. When DIP switch 5 is DOWN (factory setting), Auto Answer is disabled; S0=0 (modem answers on 0 rings, or never) has the same effect. S1 0 Counts and stores the number of rings from an incoming call. S2 43 Stores the ASCII decimal code for the escape code character. Default character is "+". A value of 128-255 disables the escape code. S3 13 Stores the ASCII decimal code for the Carriage Return character. Valid range is 0-127. S4 10 Stores the ASCII decimal code for the Line Feed character. Valid range is 0-127. S5 8 Stores the ASCII decimal code for the Backspace character. A value of 128-255 disables the Backspace key's delete function. S6 2 Sets the number of seconds the modem waits before dialing, the minimum value for which is 2. If set to X2 or X4, the modem dials as soon as it detects a dial tone (fast dials). S7 60 Sets the number of seconds the modem waits for a carrier. May be set for much longer duration if, for example, the modem is originating an interna- tional connection. S8 2 Sets the duration, in seconds, for the comma pause option. S9 6 Sets the required duration, in tenths of a second, of the remote modem's carrier signal before recognition by the Sportster. S10 7 Sets the duration, in tenths of a second, that the modem waits after loss of carrier before hanging up. If set to 255, the modem does not hang up when it loses carrier. S11 70 Sets the duration and spacing, in milliseconds, of dialed Touch-Tones. S12 50 Sets the duration, in fiftieths of a second (20 msec. units), of the guard time for the +++ escape code sequence. S13 0 S13=64 disables MNP level 3 (used for testing Level 2). S14 0 If set to 1, the modem hangs up on receipt of the escape code, returns to Command mode and sends the NO CARRIER result code. S15 0 Bit-mapped. See Appendix B. S16 0 S16=2 used for Dial Test, factory testing. S18 0 Test timer, disabled when S18 is set to 0. Used to set the duration, in seconds, of modem diagnostics, before the modem automatically times out and terminates the test. S19 0 Sets the duration, in minutes, for the Inactivity Timer, disabled when S19=0. S21 10 Sets the length of Breaks, in 10-millisecond units, that the modem sends to the computer during MNP calls. S22 17 Stores the ASCII decimal code for the XON character. Valid range is 0-127. S23 19 Stores the ASCII decimal code for the XOFF character. Valid range is 0-127. S25 5 Sets the duration, in hundredths of a second, that DTR must be dropped for the modem to respond. S27 0 Bit-mapped. See Appendix B. S28 8 Sets the duration, in tenths of a second,of the V.21/V.23 fallback delay. S34 6 Bit-mapped. See Appendix B. S38 0 Sets an optional delay, in seconds, before a forced hang-up and clearing of the Transmit buffer when DTR drops during an ARQ call. Has no effect if ATH is used to terminate a call. *Gaps in the numeric sequence indicate reserved registers.
