Help. Newbie. sendfax looses scanlines at Tx.

Hi,

a) the mgetty documentation recommends very clearly against USR Sportster
modems.  Some of them work nicely, most of them are crap.

b) your posting is missing a sendfax log file.  How shall we see what's
going on?  Run "sendfax -x5", and then send us this single call from the
sendfax.log file ("sendfax -V" will tell you where the log is).
