Re: [Hamlib-developer] input buffer cleanup

[Black M. <mdb...@ya...>]

Most any character should do what you want.

rigctld was never designed for random input.

Hi!

Is there or could it be possible to get a character, or string, that 
would clean up the rigctld input buffer?
Read through man pages did not give any hint that it already exists.


What I mean is that if we get a telnet connection to rigctld and send 
for example:

f (+linefeed)

But if rigctld is started with --vfo parameter then there is no answer 
to plain "f". It is kind of an error, but there is no indication about 
it. Rigctld just waits and waits...

if there is timeout loop waiting for "RPRT" that does not appear at all 
we could send a "cleanup" character (or string) to get rigctld ready for 
next command.
If there is no cleanup then also next command after that kind of 
situation will fail and that causes a snowball effect where several 
commands will fail.

It could be even so that the "cleanup" could be sent always before any 
real command to ensure the rigctld input buffer is clean.

As far as I can imagine that kind of cleanup character would not break 
any backwards compatibility.
