While fixing the TTY mode I found a nasty bug in the protocol engine. I will issue a new pskmail version next weekend which will fix this (users of PI4TUE can already try it, it is really lightning fast now... :) For those who are REALLY eager I have uploaded a new arq.pm to http://sharon.esrac.ele.tue.nl/psk/snapshot. Both server and client will need the new arq.pm... 73, Rein PA0R -- http://pa0r.blogspirit.com
