Thanks, Steve:

Neither Ubuntu Software nor Synaptic Package Manager list that.

I've made the suggested tweaks.

The DOSBox config file has these sections:
	* sdl;
	* dosbox;
	* render;
	* cpu;
	* mixer;
	* midi;
	* sblaster;
	* gus;
	* speaker;
	* joystick;
	* serial;
	* dos;
	* ipx; and
	* autoexec.

I have posted a query on whether serial1 should be set to modem. Might I 
try some other serial setting tweak?
