PACKET OPERATING MODES

In Chapter 4 we discussed two of the packet operating modes, Command Mode and Converse Mode. Packet also can operate in the third mode, Transparent Mode which is a data-transfer mode like Converse Mode, but is intended primarily for computer data interchange rather than human conversation. In the following sub-sections we will briefly describe all three of these modes.

Command Mode is used to enter commands that alter the MFJ-1278B's operating parameters. All the other MFJ-1278B operating modes are entered from Command Mode. When the MFJ-1278B is in Command Mode, the Command Mode prompt,

is printed at the beginning of each input line. Note, however, that if the MFJ-1278B has
