At the bottom of dca(4) it says:

BUGS
     Data loss is possible on busy systems with baud rates greater than 300.
     The dca has never been tested with modem control enabled or on anything
     but the built-in interface.

Now, given that; I'm running my hp380 (which I recently upgraded from an
hp345) with a 28.8k modem with a DTE of 38400 and it works just fine...

Of course, a 340 is a somewhat more hurting machine...
