Would someone please describe the meaning of the lights on my external
modem? The manual doesn't say anything about them. They are labelled
as:
HS, AA, CD, OH, RD, SE, TR, MR
It is a Cardinal 2400 external modem.
The reason I ask is that a few minutes ago I was logged into the
school computer via MSDOS Kermit at 1200 baud and typing a letter in
emacs when something froze. The SD light would still flash with every
keystroke, but nothing was being echoed. I couldn't even break out of
the system. Also, the MR light was flashing at about 1 Hz. The only
other lights that were on were CD and TR. So it looked like the
following:
HS AA CD OH RD SE TR MR
0 0 0 1 0 X 1 F where 0=off, 1=on, X=on with keystroke,
F=flashing at about 1 Hz
This has happened once before for unknown reasons. The only way to
break out was to tell Kermit to hangup.
Thanks in advance.
