The variable might not be called "hline" ... my memory is a little vague right now as I was up most of last night studying for an exam and I haven't gotten to sleep yet. If there is demand, I (or Rick I suppose) could re-post the patch. Note that my copy came through bitnet and is slightly munged. You should request a copy from Rick ...

Between my home 3b1 and the vax however, I'm seeing some pretty bad baud rates ... ~2500 baud whereas I'm seeing rates more like 9600 baud sending files to uunet. I haven't investigated this yet.
