right, if $_ has a prompt, evaluate it, dont read another line.
if (defined($prompt)) {
if (/$prompt/) {
goto CMD;
}

thats ios, it should have and eng marker; if it does not, then its broken.
and, ios devices and others do this from time to time; they leak memory
until they have so little free that they can not produce a full human-
display config, then they just truncate it. others produce no output, but
indicate success or lack an error. hence, the checks.
