Return cobra to local keypad control, and continue
method if onewas interrupted (Same effect adGO)
For bothRn andGn, theCobrawill transmit "RunComplete"CRwhen themethod is complete. The
systemwillwait for akeypadpress, or any character over the serial link, and then return control to
theCobra. A remote programwill have to re-sendQ toget back to control. All commands should
be terminatedwith aCarriageReturn (binary13). Allmethod#'s (n) shouldbebinary, notASCII
value, i.e. 77824901 forMR1, except theRn command, inwhich then canbe either theASCII
equivalent, or the binaryvalue, i.e. 82011313 and82491313will both start Run1.
