- ReadMe file for !Serialink. | Nick Furniss, Bracknell. (0344 54588)
-
- The procedure below will transfer a Basic program from Archimedes
- to the BBC. Both the Archimedes and BBC must be set to the same
- baud rates and data format. The default values for the Arc should
- work. Both machines must be running under Basic. The program must
- be in a version of basic acceptable to both machines.
-
- 1 Spool the tokenised Basic file to obtain a "plain language" file
- 2 Set BBC and Arc to Basic
- 3 On Arc; enter *fx3,1 to echo screen to RS423
- 4 On BBC; enter *fx2,1 to switch console input from keyboard to RS423
- 5 On Arc; enter *print <plain language file name>
- 6 Observe BBC. The file should appear as if *exec had been used
- 7 The final *spool and syntax message shows end of file. Press ESCAPE
- 8 Check there is a single Basic prompt on BBC screen
- 9 On Arc; enter *fx2,0 to switch ** BBC input state **
- 10 Check BBC to make sure keyboard input has been restored
- 11 On Arc; enter *fx3,0 to restore Arc output state
- 12 List file on BBC and if all ok, save to disc.

-
- Transfer the !Serialink.!RunImage program to the BBC by steps
- 1 to 12 above.
- Save and run the program on the BBC. Run the program on Arc.
-
- *** IMPORTANT ***
- Pressing RETURN when buffer size is requested
- gives default size of 20480. Change default
- maxsize% (at line 40) to suit BBC memory size
- if your system does not have a 2nd processor.
-
- There's a restriction on the file name length
- to suit the BBC. To get over this, copy adfs
- files for transmission, to the root directory,
- and restrict the copy-to file's name to seven
- characters. <xcom> is suggested. Similarly,
- use a relay file for saving the buffer, (Arc)
-
-
- All instuctions for operation of the comms package appear on the
- screen. On starting the program, you are asked for a buffer size.
- Pressing return gives the default. The buffer is then initialised.
- You should then press SPACE and ESCAPE when requested. This brings
- up a Cmd.? prompt on the bottom section of the screen. Pressing <H>
- displays the commands for about 2 seconds. Communication will not
- take place when the Cmd.? prompt is displayed. To cancel, press
- ESCAPE again. All commands are given by pressing a single key.
- Commands are NOT case sensitive. For commands, the bottom window
- of the screen is in page mode. Press SHIFT to scroll the window.
-
-
- Experiment with the linked system and add your own procedures.
-
- Good luck.
