	My experience with the Racal-Vadic 1200V modem dealing with these
problems have been attributed from the DTR not being enabled. Racal-Vadic
requires pin 20 (DTR) to be enabled for ALL auto operations. This includes
auto dialing and auto-answering. My suggestion to you is to check the 
following;

		Option 4 (auto-answer) set to 1 (enabled)
		Option 6 (Dial Mode) set to 2 (Tone)
			- This is usually required for most phone lines.
			  The Racal-Vadic seems to dial better this way.
		Pin 20 (DTR) is above +3vdc or enabled by jumpering pin 20
			to pin 9 (Test Voltage) which will enable DTR all
			the time. 

	I hope this information will help you out. Good Luck!
