Soundcard software that does not automatically insert a CR-LF
sequence after sending 72 characters is no less compatible with
the "RTTY standard" John cites than are his mechanical teleprinters.
If I'm using a mechanical teleprinter in a RTTY QSO and I type more
than 72 characters, does the teleprinter automatically insert an
outgoing CR-LF sequence? No, it does not. The operator is
responsible for conformance with the standard.
If I'm using soundcard software in a RTTY QSO and I notice that I'm
coming close to having typed 72 characters and so strike the Newline
key, does the software generate a CR-LF sequence? I know that mine
does. Again, the operator is responsible for conformance with the
standard, and that conformance is no less difficult than with a
mechanical teleprinter. In fact, its one keystroke easier.
John requested automation to facilitate compliance with the
standard -- compliance that is currently an operator responsibility
whether one is using a mechanical teleprinter or soundcard software.
His request was for developers of soundcard software to include the
automation. I simply pointed out an alternative approach that John
could implement himself, rather than depend on the coincident good
graces of the multiple developers who produce soundcard RTTY
software.
