EXAMPLE:The hostwill receive upload recordsfroma hand-heldcomputer,on
alogicalchannel,until the upload is complete.Afterthe upload is
complete, the hostwill receive download datarequests,on the same
logicalchannel, forthe hand-heldcomputer.The hostwill respond
with download data until finished,atwhich point, an end-of-datare-
cordis sent. The hostwill then receive and end-of-session record
whichreportsthe statusof the hand-heldcomputersession.
