This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
MANUAL FOR 2ND SERIAL PORT (6502 ROM image)
By Robert Sprowson
This file describes the ROM image 2NDSERIAL, which drives the associated
second serial port card hardware which contains a 6850 serial chip so
the machine can have two ports in use simultaneously. The image requires
at least one 2k bank of Sideways RAM or to be put onto a ROM to work.
Instructions
At any command prompt, eg. the BASIC prompt ">", type
On a Master: *SRLOAD U.2NDSERI 8000 <socket#>
*INSERT <socket#>
where <socket#> may be 7, 6, 5 or 4
On a machine with SWRAM: *LOAD U.2NDSERI 8000
and press <CTRL><BREAK> to initialise.
On reset, the software will claim 3 pages of memory for its private use.
One page of this is for new buffer management software and the other two
are for serial input/output buffers, which means it cannot be in the
'hidden' workspace on a Master series machine.
You can control all the settings you would expect to be able to do
with the normal on-board serial port such as baud rates, data formats,
etc... Firstly, you must type *COM2 at the command line, so that changes
to settings you make refer to the new serial port, then simply issue any
*FX calls which you rewuire to set up the serial port (referring to the
BBC Micro User Guide).
To switch back to controlling the built-in serial port, issue a *COM1
command. So, for example, setting baud rates:
*COM1 <talk to the on-board serial port>
*FX 7,3 <sets receive speed of internal port to 300>
*FX 8,4 <sets transmit speed of internal port to 1200>
*COM2 <directs osbyte to the second serial port>
*FX 7,6 <sets receive speed of the 2nd port to 4800>
Technical Information
The following conditions prevail at power up:
OSBytes refer to: COM1, the internal port
Baud rate: 9600 transmit and receive
Parity: None
Stop bits: 1
Data bits: 8
The input buffer id is 9 and output buffer id is 10.
Events will be generated which may be of interest to the programmer
if an RS423 error occurs or a buffer becomes full or empty:
"RS423 error" .... the lost byte is passed in Y, the second serial
card's 6850 register is passed in X shifted right by
1 place
"Input buffer full" .... the unsuccessful byte is in Y and X=9
"Output buffer empty" .. enters with X=10
Known Problems/Future Enhancements:
No known problems.
Could implement the remaining three unimplemented OSBytes.
History:
v0.63 Modified test code to allow it to be run from ROM
v0.68 Added OSByte interface
See additional file (V.+2NDPO2) for Supported *FX Calls.
