Response:

	We use the $set host /dte command extensively here and with
	great success and usefullness.

	It is not true that this command can only be used with DEC
	modems.
	The  $set host/dte  command serves as a mechanism to logically connect 
	you with the specified line and route the input from your terminal or 
	device down that line.  Therefore you can use this command
	to connect to any line with any number of possible devices
	connected to it.  As one of our devices we use Hayes 2400 
	smart modems and it works fine.  We use this command extensively
	when Kermitting files.

	However the command $set host/dte/dial=(NUMBER:number) TTXX:
	uses an image called Sys$library:dte_df03.exe to automatically 
	call the specified number using the DEC DF03 modem protocol.

	Alas, the sources for the image are supplied by DEC in the file
	Sys$examples:dte_df03.mar to be used as a template for users to 
	modify the code to talk whatever protocol your modem speaks.

	We have successfully converted the code to talk to 
	our Hayes modems and built the image Sys$library:dte_hayes.exe
	and then use the command:
	$set host/dte/dial=(NUMBER:number,MODEM=hayes) TTXX:.


	A possible suggestion to your line allocation question might be to
	put an Access Control List (ACL) on each of the lines and then Grant
	these ID's in Authorize to the desired users.  As a side benefit, this
	could provide a kind of load leveling mechanism.
