060: Set Up Serial Port Options
This command allows you to turn several options on or off for the main serial port. Each of these
options is discussed below.
The first is whether or not the serial port converts all characters that you type to upper case or not.
The default is to convert them, because the controller normally expects everything in upper case.
When the DTMF digits ‘A’, ‘B’, ‘C’ and ‘D’ are entered, the controller always considers them to be
upper case. Converting all of the characters received from the serial port makes it impossible to do
a few things however, such as programming serial messages that contain lower case letters.
The second allows you to choose whether the controller will send a carriage return and line feed at
the end of each line (the default) or just a carriage return. The latter might be useful in situations
where the line feed messes up a modem or packet radio. Most communications programs can
automatically add the line feeds back in when they receive a carriage return so that the screen will
scroll, rather than printing each line over top of the last one. If you are trying to make a modem
dial you, you will have to turn line feed sending off or when you send "ATDT<phone number>" the
controller will follow it with a CR/LF (carriage return and line feed). The CR will tell the modem
to start dialing. The LF will make it stop dialing - if a modem receives any characters from the
controller while it is dialing, it will abort.
The third determines whether serial messages that are generated by commands that are executed by
DTMF are suppressed or printed. If they are suppressed (the default), the only serial messages that
will be printed are: the reset/copyright message, serial responses to commands executed from the
serial port (not DTMF), and serial messages sent with Command 162.
The fourth is whether the serial is queued (buffered) or not. Buffering is not currently supported,
so this digit has no effect.
<060> x y Set case sensitivity and line feeds.
<060> x y z Set case sensitivity, line feeds and suppression.
<060> x y z q Set case sensitivity, line feeds, suppression and queuing.
<060> 0 1 1 1 Set all settings to default values.
Parameters:
- 060 is the default command name.
- X is 1 to make the serial port case sensitive (no automatic conversion to upper case)
0 to make the serial port convert all characters entered to upper case
- Y is 1 to send line feeds (the default) or 0 to suppess them
- Z (optional) is 1 to suppress serial (the default) or 0 to send serial caused by commands
entered from DTMF
- Q (optional) is 1 for queued serial (the default) or 0 to send it before continuing
