Commands to the VX4802 may be entered in upper or lower case. However,
to avoid confusion between the alphanumeric characters; e.g. one (1) and L
or zero (0) and o, all commands are shown in the case which provides the
greatest distinction. Use special care when interpreting these characters.
NOTE
. If at any time you observe a QE response or an ERR light from the
VX4802 or VX4801, you must perform a status query (ibwrt “qa”, ibrd 100) to
read and clear the error condition.
