Someapplicationsrequirethatthehostterminal(orserver)approveor

Theseapplicationsrequirethatthehostmaintaincontroloverthe

ThefollowingcriteriamustbemetfortheHostACKtoworkcorrectly:
• Thecordlesssystemmustbeconfiguredfor“HostPortRS‐232”
(TerminalID=000)
• RTS/CTSisdefaultedoff.Youmustenableitifthehostsystem
requiresit.
• HostACKmustbeenabled,seeChapter2.
• SystemperformancedegradeswhenusingHostACKatrates
lowerthan9600.
• Thehostterminalsoftwaremustbecapableofinterpretingthe
