I am not sure if it works but you could try to do the following:

cat /dev/midi00 >dumpfile

start the sysex transfer

when finished
press CTRL-C
the dumpfile will contain the dumped data.

then to playback the data
first start sysex receive on your midi module
then do
cat dumpfile >/dev/midi00

which should send back the data to the midi port.

I tried here a cat /dev/midi00 >file

and pressed and released two keys on the MIDI keyboard,
then pressed Ctrl-C
and looked at the binary contents of the files:
it contained exactly the two note-on and the two note-off messages
and had a length of 12 byte.

I have currently no external MIDI expanders here so I can't try
to do the dump.

Benno.
