Specifications
Packet:
The TRACE command activates the AX.25 protocol display. When TRACE is ON all
received frames are displayed in their entirety, including all header
information. The TRACE display is shown as it appears on an 80-column display.
The following monitored frame is a sample:
W2JUP*>TESTER <UI>:
This is a test message packet.

The byte column shows the offset into the packet of the first byte of the line.
The hex display column shows the next 16 bytes of the packet, exactly as
received, in standard hex format. The shifted ASCII column decodes the high-
order seven bits of each byte as an ASCII character code. The ASCII column
decodes the low-order seven bits of each byte as an ASCII character code.
FAX:
When Operating in FAX mode, TRACE is ON, and PRFAX is OFF, the graphics escape
sequences and dot data are sent to the terminal with each byte expanded to two
Hexadecimal characters. This helps get around the limitations of many terminal
programs that do not allow 8-bit data to be saved to disk as an ASCII file.
Interspersed command prompts and even the L and R commands would have no
effect on the final data and it could be translated back to binary data with a
computer program.

Trans Immediate Command
Mode: All Host: Not Supported
_______________________________________________________________________________
TRANS is an immediate command that switches the PK-232 switch from the Command
Mode to Transparent Mode. The current state of the radio link is not affected.
Transparent Mode is primarily useful for computer communications. In
Transparent Mode "human interface" features such as input editing, echoing of
input characters, and type-in flow control are disabled.
o Use Transparent Mode for transferring binary or other non-text files.
o To exit the Transparent mode, type the COMMAND character (default <CTRL-C>)
three times within the time period set by CMDTIME (default 1 Second).

_________________________________ Parameters: _________________________________
ON - Software flow control for the computer or terminal RECEIVING data is
activated in Transparent Mode.
OFF - Software flow control for the computer or terminal RECEIVING data is
disabled in Transparent Mode.
