Re: flexfax: Re: egetty and vgetty

Thanks very much for the example, the only difference between what you are
doing and what I was doing is that you are issuing ATA before exiting
egetty. 100 to 1 that was my mistake, now I realize that of course hylafax
should expect that start the fax call handling is the responsibility of
the egetty program. And of course egetty should also reinitialize the
modem before issuing the ATA command. 

If this works I will still read the changes sent to me and try to see what
he did. I'll also send you a few lines with the changes that I recommend,

Thanks very much!
