the port's Linux device name, and
the baud rate currently in operation on the port.
You can query a single port by using the port number or key as arguments to the gnblocks command:
gnblocks 2 gnblocks 0x7002 gnblocks 28674
(In the last example, 28674 is the key ID 0x7002 expressed in decimal: hex 7002 = 7 × 163 + 2 = 28674.)
Another way to find out the index, key ID, name or device name of a particular serial port is to issue the command serialmap. A line will be output for each serial port, in the form
Port 0, Key 7000, name tts0, device /dev/ttyS0, baud 115200
where port and baud are in decimal, and Key in hexadecimal. The related command serialmap
Digitizer status
The Gü ralp DM24mk3 digitizer outputs status information as a separate stream. If you have a DM24mk3, you can monitor this stream with the command
dm24mk3cds
Whilst this program is running, it will output any status blocks it receives on that port directly onto your terminal:

gps_fix=2 (0x32) gps_mode=A (0x41) gps_control=255 (on) gps_power=255 (on) gps_offset=167 ticks busy_counter=0 ticks
locking=0 unlocking=0 centering=0 calibration V N E
The information given, after the stream ID (which will always end in CD), is as follows:
