6.5.3 Formatting Your Transmitted and Received Text
The default configuration of the PK-232 RTTY parameters are designed
for natural conversation and traffic. Sometimes it is desired to
alter how your typed text looks on the screen of the station you are
talking to. The commands ACRRTTY and ALFRTTY allow for customizing
the Carriage Return and Linefeed characters in your transmitted text.
To allow for changing how received text is displayed on your screen or
printer, see the ACRDISP and ALFDISP commands in the Command Summary.
MARS operators have some special requirements for RTTY operation and
displaying text. To accommodate these, the CRADD and MARSDISP
commands are included and should be reviewed in the Command Summary.
6.5.4 Sending a Synchronous Idle or DIDDLE
Some RTTY users like to send an idle signal when no data is being
transmitted. To allow for this the PK-232 has the DIDDLE command.
See the Command Summary for more information.
6.5.5 Echoing Transmitted Characters As Sent
Since Baudot RTTY at 45 baud is rather slow, some users like to know
just when the characters they are actually being sent. The EAS
command when turned ON will Echo characters to the display only when
they are sent over the air.
6.5.6 Sending Only Complete Words
Some RTTY users like to have their words sent out only when they are
complete. This allows the word you are currently typing to be edited
as long as you have not typed a <Space> character. Turning WORDOUT ON
activates this feature. See the Command Summary for more information.
6.5.7 Operating on the Wrong Sideband
In RTTY operation it is important to be operating on the correct
sideband, otherwise other stations will not be able to copy your
transmissions. If you find another station operating on the wrong
sideband, you can reverse your receive sense with the RXREV command so
you will not have to change sidebands yourself.
Similarly, if someone tells you that you are on the wrong sideband,
you can correct your transmit signal sense with the TXREV command.
See the Command summary for more information on these commands.
6.5.8 Unshift-On-Space (USOS)
The Unshift-On-Space (USOS Command) automatically changes the received
Baudot/Murray code characters to the LETTERS or lower case condition
after any "space" character is received.
When operating Baudot RTTY under poor conditions, a received LETTERS-
SHIFT character can be garbled, or another character can be wrongly
interpreted as a FIGURES-SHIFT character. Turning USOS ON helps
reduce reception errors under these conditions.
