probably not very helpful, but I remember my Calypso modem on GTA01 sometimes
getting into a loop where it would only give a +CME error on anything I do until
I reset it.  It was not reproducible - when it happened for the first time, I
tried to reproduce it and couldn't, but another day ran into it again.  It was a
long time ago.

I don't know what the error code was because I was using the AT+CMEE=2 mode
(textual errors) so it was something like:

+CME: Operation in progress

or something similar, but it was a non-standard error (i.e. it was not in the
GSM specs when I checked).  I only hit it when manually using the serial port
with "cu".

The modem was printing this error on every *character* I typed, not every
command (unless pasting commands).  So if I typed AT+ABC slowly, I would get:

+CME: Operation in progress
+CME: Operation in progress
+CME: Operation in progress
+CME: Operation in progress
+CME: Operation in progress
+CME: Operation in progress
