Get the current message tag.
In a system where the message tag is encoded as described in the DMS command, the
VoiceDSP processor return value indicates that the message is a new ICM in mailbox
Number 6.
GNM
Get Number of Messages tag_ref tag_mask
Returns the number of messages whose message tags match the tag_ref parameter. Only bits set in
tag_mask are compared, a match is considered successful if:
message tag and tag_mask = tag_ref and tag_mask
where and is a bitwise AND operation.
The tag_ref and tag_mask parameters are each two bytes; the return value is also two bytes long.
See “Message Tag” on page 2-3 for a description of message-tag encoding. If tag_mask = 0, the total
number of all existing messages is returned, regardless of the tag_ref value.

Get the number of messages which have bit 0 cleared, and bit 1 set, in their message
tags.
VoiceDSP processor responds that there are five messages which satisfy the request.
GSW
Get Status Word
Returns the 2-byte status word.
STATUS WORD
The VoiceDSP processor has a 16-bit status word to indicate events that occur during normal opera-
tion. The VoiceDSP processor asserts the MWRQST signal (clears to 0), to indicate a change in the status
word. This signal remains active until the VoiceDSP processor receives a GSW command.
The status word is cleared during reset, and upon a successful GSW command.
