Tom,
In ASCII code (used for PSK), LF and CR are two separate characters. LF
= hex "A" and CR = hex "D".
A true CR has no line feed associated with it, and a LF has no CR
associated with it.
So it depends on the application doing the sending (and perhaps also on
the application receiving) to determine just what happens.
You asked about FSK - and that is similar. If you are analyzing the
characters sent in BAUDOT code, the same thing applies but LF is Hex "2"
and CR is hex "8*.
So if you are developing your own code, you will have to handle them
separately. Normally folks expect the "Enter" key on a keyboard to do a
CR and LF while the down arrow does a LF only while the "home" key would
do a CR only. Applications normally follow those conventions, so if you
are looking at it from a keyboarding standpoint, the Enter key should do
both when using a normal application.

Hi
Is it possible to transmit a Carriage return/line feed with FSK and psk?
If so is it a actual carriage return?
Thanks, Tom
