SEQUENCE    select escape sequence 
The escape sequence is part of the Hayes compatible aspect of modem operation. 
 
It is explained in more detail in the Modem User Guide, and also with the sequence event handler ON SEQUENCE. 
 
The possibility of an escape sequence occurring can be enabled with SEQUENCE ON; disabled with SEQUENCE OFF. 
 
The escape sequence character can be set with...

SGN    get sign of number 
SGN is used to determine the sign of a number and returns three possible values, depending on whether the test value is 
negative, zero or positive. 
 
The following apply: 
SGN 56
returns 1   
SGN 0
returns 0   
SGN -45
returns -1   
Examples: 
Dif=SGN(X1-X2)
X=SGN(y)
Syntax: 
[num-var] = SGN [integer]

SOUND  (MODEM)  make a sound 
SOUND has two optional parameters frequency and duration, set in hundredths of a second.  If the parameters are left out, 
then 2000 Hz and 250 ms are taken by default. 
 
The command SOUND, without MODEM behind, will produce a sound on the speaker only, by toggling the speaker-mute-bit 
(see VOICE) with the desired frequency. 
 
The command SOUND MODEM will...

SPC$    repeat spaces 
The SPC$ string function produces a string containing the specified number of ASCII Space characters. 
Examples: 
Title$=Name=SPC$(10)+Age+SPC$(5)+Sex
PRINT Port number+SPC$(20)+VAL$(port)
Syntax: 
[string-var]=SPC$[integer 0..255]

SPEAKER ON/OFF    speaker control 
The SPEAKER command is used to enable or disable the modems internal loudspeaker.  Same as AT M2/0. 
 
If a headset is connected to the Argus, the SPEAKER OFF command disables the headset as well and is therefor not 
suitable to control the speaker while the headset is active.  In that case the speaker-mute-bit must be set or cleared with 
POKE (see VOICE)....

SPEED [number]    line speed select 
This command is used to set S-register 51 within the programming environment.  Same as AT S51=x or
SREG51=[num].  SPEED is used when connecting as a modem or fax. 
After connection, S-register 50  (bits0-5) is set to the connected speed as listed below: 
 
 1 = 1200 (V22)  38 = 28800 (Vfast) 
 2 = 2400 (V22bis)  39 = 26400 (Vfast) 
 3 = 300  (V21)  40 =...

SPEED BUFFER ON/OFF    speed buffer on/off 
The command is another way to set S-register 52 within the programming environment.  Same as AT S52=1/0 or 
SREG52=1/0. 
 
When speed buffering is enabled (default), there is no relationship between the modem-speed on the line and the speed at 
the serial ports of the modem.  The ports will only change their speed when AT is entered at a new baud...

SREG    set/read S-registers 
SREG is used as another way to set or read the 80 available S-registers that the modem keeps in memory.  These registers 
are holding various types of parameters which are used by the modem operating system for all sorts of purposes.  Most of 
them are mentioned throughout this manual.  For further information, see the Modem User Guide. 
 
This way of manipulating...

STOP    halt program execution 
STOP terminates program execution, and is most often used during program debugging to temporarily halt a program so 
that variables can be examined. 
 
Execution may be restarted by entering a GOTO command for the line following the line containing the STOP command. 
 
A special command to control the STOP button is: 
STOP ON/OFF
With STOP ON, the button will...

TIME$    read or set time 
TIME$ is used to read the current time as a string or to set the clock. 
 
The string has the format hh:mm:ss (hour, minutes, seconds) for input as well as for output. 
Examples: 
TIME$ = 14:20:00
Tstamp$ = TIME$
Syntax: 
TIME$ = [string]
[string-var] = TIME$
