Hi All,

AEA's PK-232MBX, PK-900, DSP-1232, and DSP-2232 all had the option to have PACTOR I support.  For some modes that these TNCs are capable of, the RS-232 DCD line could be configured via a command to change state, under circumstances documented in the manual.  I don't happen to recall exactly what all of the circumstances were, but, for example, having the TNC achieve a CONNECTED state in Packet was one of them.  AEA also included a host mode among its serial interface modes, one designed for an explicit poll/response handshake for all interaction, such that no data transfer from the TNC to the computer occurs without having been requested by the computer.

Hope that helps!

73, Bob, KD7NM
