#Aterm Problems
Todd, if you receive a spurious ^S from line noise or whatever, the ^Q you
type will not be sent, and therefor not echoed, to get you out of the lockup. I
think there must be a way (short of closing the serial port) to escape from
this condition, but I haven't seen it yet.
Use your judgement when disabling/enabling Xon/Xoff. If you are sending a
file to a host, the PROMPT character will normally be enough to throttle the
sending speed to a rate that the other side can handle, but not always.
Sometimes you just need to have it enabled so that the host can stop your
transmission if it starts to choke on it.
Regards, Larry.
