GET    get byte (with wait) 
GET is used to obtain the next byte from the specified input buffer, and returns an integer between 0 and 255.  Program 
execution is suspended until data becomes available.  If no port is specified, the default input port as defined by IPORT is 
assumed. 
Examples: 
Code=GET
Char=GET#1
REPEAT UNTIL GET=13
PRINT GET#2
Syntax: 
[num-var] = GET ( #[port] )

GET$    get character (with wait) 
GET$ is used to obtain the next character from the specified input buffer, and returns a 1-character string.  Program 
execution is suspended until data becomes available.  If no port is specified, the default input port as defined by IPORT is 
assumed. 
Examples: 
Ch$=GET$
A$=GET#2
REPEAT UNTIL GET$#2=Y
PRINT GET$#4
Syntax: 
[string-var] = GET$ ( #[port] )...

GOSUB ... RETURN    jump to subroutine 
The GOSUB command causes program execution to branch to the specified line number or label.  Execution proceeds from 
this line until a RETURN command is encountered, at which point execution resumes at the command immediately following 
the GOSUB.  The section of code executed by the GOSUB is referred to as a subroutine, and may be executed any number...

GOTO    unconditional jump 
GOTO causes an unconditional branch to the specified line number or label. 
Examples: 
GOTO 70
GOTO %Check_Password
Syntax: 
GOTO [line-num | label]

HANDSHAKE    select/enable handshaking 
HANDSHAKE is used to select the action taken when an input buffer is almost overflowing during receipt of data.  Correct 
selection of the type of handshaking to be used is necessary to avoid loss of data. 
 
Each port on the modem has a 256-byte input buffer.  When characters are received at a higher speed than they can be 
processed, the input buffer...

The handshake of the input ports has to be set with the HANDSHAKE command.  This is normally HANDSHAKE RTS.  
When the data stream on a linked port is not to be monitored by a program, then the command HANDSHAKE LINK OFF 
should be used. 
 
The HANDSHAKE command may specify one or more port numbers, but if these are omitted, the default port as defined by 
OPORT will be assumed. 
 
After the...

HANGUP    disconnect a call 
HANGUP is used to terminate a call and is identical to the command HOOK ON and the modem command AT H0. 
 
The command itself will not cause an ON HANGUP event. 
 
HANGUP will also put the modem-chip in sleep-mode, if bit6 in S-register 64 is set (see RESET MODEM 2). 
Examples: 
HANGUP
MATCH#3 ABC , 10 : IF MATCH HANGUP
Syntax: 
HANGUP

HOOK    hook control 
HOOK is used to control the modem relay that puts your modem on-line. 
 
HOOK OFF is the same as the modem command ATH1. 
 
HOOK ON is the same as the command HANGUP and the the modem command ATH0. 
 
HOOK on its own can be used to toggle between the two states of the relay. 
Examples: 
HOOK
HOOK OFF
HOOK ON
Syntax: 
HOOK (ON|OFF)

HOUR    read/set hour of day 
HOUR is used to read or set the hour of day on the internal clock/calendar. 
 
The clock uses the 24 hour system, so that when reading, HOUR will return an integer from 0 to 23. 
 
Similarly, when setting, the hour number from 1 to 23 must be specified; an incorrect value will cause the current setting to 
remain unchanged. 
Examples: 
HOUR=14
IF HOUR > 12 THEN...
