See Also 3.1.2.4 and 3.2.5
READYCK(=)
Purpose Read or set a flag that is cleared by a Not Ready condition.
Syntax “READYCK=1”
“READYCK”
Defaults “READYCK=1”
Remarks The internal ready check flag is cleared whenever the molbox
RFM reaches a Not Ready (NR) condition. The "READYCK"
command will return the status of this flag. This flag can be set
only by sending the "READYCK=1" command while the molbox
RFM is in a Ready (<*>) condition. If you send the
"READYCK=1" command when the molbox RFM is in a Not
Ready (NR) condition, the reply will be "READYCK=0".
If you set READYCK=1 when the molbox RFM achieves a Ready
(R) condition, you can use READYCK later to determine if a Not
Ready (NR) condition has occurred. If NR has occurred,
READYCK will return "0". If NR has not occurred, READYCK will
return "1".
Example Command:
Reply:
“READYCK=1” (set the flag)
“READYCK=1”
Command:
Reply:
“READYCK” (query for flag status)
“READYCK=1” (has been ready since setting flag)
Errors ERR# 6: The argument is not a 1.
