ENDWAIT
Pauses the script for a given number of half-seconds, and waits for one of
several strings. E.g.
WAIT 10
“No carrier” GOTO tryagain
“Hangup” GOTO closeconn
ENDWAIT
SEND “ATDT91011992220”
pauses for 5 seconds before proceeding with the next command in the
script (‘SEND’). If, during that time, the MC 218 receives “No carrier”
from the remote machine, it will carry out the ‘GOTO tryagain’
command. Similarly, if the MC 218 receives “Hangup” during the 5
seconds, the script will jump to the ‘closeconn’ label. WAIT requires a
matching ENDWAIT command.
W
HILE WHILE <exp> DO

E
NDWHILE ENDWHILE
Carries out a given command while a certain condition is met. E.g.
WHILE R$<>“OK” DO
SEND “AT”
ENDWHILE
sends the “AT” string as long as R$ is not equal to “OK”.
Note: The important difference between REPEAT…UNTIL loops and
WHILE…DO…ENDWHILE loops is that REPEAT…UNTIL always
executes the specified action at least once, and ceases to do so when a
condition is met. By contrast, WHILE…DO…ENDWHILE checks for a
condition before ever carrying out an action, so if the condition is not met, the
action will not be executed at all.
