If a reset occurs while no program is running, the program present in memory at the default value of PBOT will be executed. 
 
This is similar to typing RUN, except that program variables will not be reset. 
(c) Program running at moment of reset 
If a reset occurs while a program is running, program execution will halt and the error message RESET/START at
line ... will be given

ON RING    RING event handler 
The RING event lets you know when a call comes in, allowing your program time to do whatever you want it to before 
answering. 
 
Try entering these 3 lines: 
10 ON RING SOUND 2000,100
20 REPEAT UNTIL FALSE
RUN
If you now disconnect your phone from your modem, and dial the number of your line from another location, your modem will 
RING for you!

ON SEQUENCE    Esc. sequence event handler 
The escape sequence event allows you to interrupt whatever the modem is doing by use of an escape sequence.  This event 
will only occur if the escape sequence is also enabled by SEQUENCE ON. 
 
The modem S-registers S2 and S12 also influence the escape sequence. 
 
When an escape sequence has occurred, you can read the port number where it happened...

ON SLASH    AT scan event handler 
ON SLASH is used to react to the character string A/ typed at one of the serial ports and works simular to the ON AT 
event.  The ON SLASH event will only happen if A/ is detected on a port which has been previously set to A/-scan using 
the command AT SLASH. 
 
When the ON SLASH event occurs, the port number of the port which received the A/ can be found in...

ON TIMEOUT    timeout event handler 
ON TIMEOUT can be used to execute a particular sequence of commands at regular time intervals, and therefore provides 
the basis for carrying out background tasks. 
 
A single numeric parameter is used to specify the time interval in seconds from 1 to 65535.  When executed, the timer will 
count down until the value is 0, and then reset to the original...

OPORT    default output port 
OPORT is a system variable that defines the default output port number(s). 
The following commands will use the port(s) defined by OPORT if no port is specified in the command itself: 
ACTIVE DSR OUTPUT REPORT
BAUD ESCAPE PARITY SBITS
CLEAR INPUT HANDSHAKE PRINT SEND
CLEAR OUTPUT INPUT PUT XOFF
CTS LENGTH PUT$ XON
DIR LINK RECEIVE
 
OPORT differs from IPORT in...

ORI    output ring indicator 
RI is the RS232 signal used by modems to indicate that an incoming ring has been detected; i.e. that a call has been 
received. 
 
RI is also an output from the modem on the RS232 ports. 
 
There is of course only one RI for both serial ports, because a modem can either receive a ring or not receive a ring. 
 
The RING output is controlled by the internal...
