with FLDigi as soon as I get it working on that machine..
Don't know why, but Ed's comment about something being "stuck"
made me flail away.. For some reason--even though the BIOS was set to
0x3f8 and 0x2f8, ints 4 and 3--I had the problem.. When I changed the
BIOS to "auto" for both; all is now well; at least with ttyS1..
For kicks I ran several RS232 diag pgms again and two failed
with three others saying all is well... Ugh... HI..
Thanks all for the input and prodding.. Vy 73..
