The '''DLV11-E asynchronous serial line interface''' card (M8017) was a [[QBUS]] [[peripheral]] for the [[PDP-11]] series of computers which provided an [[asynchronous serial line]] on a single [[DEC card form factor|dual-width]] card.

It provided [[EIA RS-232 serial line interface|EIA RS-232]] connectivity, at speeds of 50 to 19,200 [[baud rate|baud]]; it also had full [[modem]] control. Line connection was via 40-pin [[Berg connector]] headers on the top edge of the card, using the standard [[DEC asynchronous serial line pinout]].

==Programing interface==

Like the ancestral [[KL11 asynchronous serial line interface|KL11]], the DLV11 has 2 device [[register]]s for the receive side (one Control and Status Register - CSR - and one data [[buffer]] register), and similarly, two for the transmit side. Each line has two [[interrupt vector]]s - again, one receive, and one transmit.

For the PDP-11 main console (which is always a KL11/DL11 compatible device), the standard is that 0777560 is the base address (so the receiver registers are 0777560-2, and the transmitter are 0777564-6), and 060 is the base vector. It can be set to [[halt]] the [[Central Processing Unit|CPU]], or [[bootstrap|re-boot]] the system, when a '[[asynchronous serial line|break]]' is seen.

The first line after the console is always assigned the address 0776500, and vector 0300. Additional lines are assigned addresses and vectors immediately following, for DL11's #1-#16 (i.e. 0776500-676 and 0300-0476).

==Layout==

The 'Revison D' [[printed circuit board|PCB]] layout is significantly different from the earlier ones; it is easy to recognize this version visually, as the large [[asynchronous serial line#UART|UART]] chip is parallel to the long axis of the card. This version is not covered in most DLV11-E documentation; it can be found in the ''"Microcomputer Products Handbook"'' (1985), on pg. 22-3.
