# DL11 echo tester
|
|
|
|
The `dl11echo` code simply echos any input entered on the console DL11 device.
|
|
Default is direct echo, only modification is to add a `LF` after `CR`.
|
|
Other modes can be selected by two ESC plus a character:
|
|
```
|
|
ESC + ESC + u -> uppercase
|
|
ESC + ESC + l -> lowercase
|
|
ESC + ESC + o -> octal echo (16 per line)
|
|
ESC + ESC + a -> direct echo
|
|
```
|
|
If the board has LEDs they will show an RSX-style light pattern.
|
|
|
|
### Start on w11
|
|
See general notes on
|
|
- [FPGA Board setup](../../../doc/w11a_board_connection.md)
|
|
- [Rlink and Backend Server setup](../../../doc/w11a_backend_setup.md)
|
|
|
|
Start `dl11echo` on an FPGA board or a GHDL simulation with
|
|
```bash
|
|
console_starter -d DL0 &
|
|
ti_w11 <opt> @dl11echo_run.tcl
|
|
```
|
|
with the options `<opt>` as described in
|
|
[Rlink and Backend Server setup](../../../doc/w11a_backend_setup.md).
|
|
|
|
### Start on SimH
|
|
```bash
|
|
console_starter -s -d DL0 &
|
|
pdp11 dl11echo.scmd
|
|
```
