TL-130400-1001Record Code AP:17.3 Record Code AP, Figure 17.3, defines the common
Data Systeminterface parameters for each APM (Asynchronous Packet
Asynchrouous PortManager). This record code is only used for asynchrouousports, and an entry for each APM must be found here.
There are three types of parameters that are defined for each of
the terminals or groups of terminals. They are:
.=.
