5.2 Command structure
The PTC commands are similar to the commands of a TNC with TAPR software this
makes it easy to learn and handle.
There are commands with and without arguments. If an argument is possible the
argument has to be separated from the command by at least one space. A command's
current argument setting is displayed if the command is entered without an argument.
Nearly all commands can be used in abbreviated form to save keystrokes. The shortest
keyword of a command consists of the fewest number of characters that uniquely identify
it, e.g. you may type C instead of Connect. All command inputs are internally converted
to upper case, so both character shifts may be used. All commands are listed below,
significant mnemonics are printed in capital letters. The short form of the SERBaud
command is SERB.
5.3 Menus
The PTC-IIIusb commands are combined into different function groups, so called menus.
The different menus are the following:
• Packet-Radio
• Audio functions
• FAX/STTV
• Transceiver controlling
• System test
Last not least the main menu with the PACTOR/AMTOR/RTTY/CW/PSK31 commands.
The command prompt indicates the menu you have already selected. The following table
shows the prompts for the different modes.

The separated function groups are for a better overview but this is not their only reason.
PACTOR for example has for the short wave port the command TXDelay and for the
Packet-Radio port also the TXDelay command. The same is with the Mycall command
for PACTOR and Packet-Radio.
The grouping of the commands within the menus allows to choose the right commands
for the selected modes or functions.
