Serial Receive (sr) is a small utility for Amiga that will help receiving files over the serial port with a null-modem cable.
So, you have your amiga and a pc and you wonder how to transfer files from pc to amiga.
This page http://www.boomerangsworld.de/cms/vc/amiga_transfer.html is nice to give you a start. It describes the necessary port configurations both on pc and amiga, and finally a small program (a few lines of source code) which is in AmigaBasic for pre-2.0 amigas and Arexx for >=2.0 amigas that will help you transfer a file from pc to amiga.
The simplest way would be to go on amiga side and type in a shell
type ser: >file
and on the pc side (assuming linux)
cat file >/dev/ttyS0
One unfortunate thing is that amiga's
type
command doesn't work for binary files after Workbench1.3. For text files it works no matter the version of the workbench.
That is the reason you either need to write the following AmigaBasic
' Written by Wolfgang Stoeggl (1998)
INPUT "filename? ",file$
INPUT "size (bytes)? ", size&
PRINT "Now send the file!"
OPEN "ser:" FOR INPUT AS #1
OPEN file$ FOR OUTPUT AS #2
n% = 1024
WHILE LOF(2) < size&
diff&=size&-LOF(2)
IF diff&<1024 THEN n%=diff&
t$=INPUT$(n%,#1):PRINT #2,t$;
LOCATE 5,1
PRINT LOF(2)
WEND
PRINT "Received file: ",file$
PRINT "filelength =", LOF(2),"bytes"
CLOSE
END
or the following Arexx
/* receive.rexx
** Written by Wolfgang Stoeggl (1998, 2004) */
say 'Filename?'; pull file
say 'Bytes?'; pull size
say 'Now send the file!'
open('1','ser:')
open('2',file,'W')
n = 1024
lof = 0
do while lof < size
lof = seek('2', 0, E)
diff = size-lof
if diff < 1024 then n = diff
t = readch('1', n)
writech('2', t)
say lof || '0b'x
end
say 'Received file: 'file''
say 'Filelength = 'lof' bytes'
close('1'); close('2')
exitIn both programs the basic idea is that you provide a filename and the file's size for the amiga side to know how many bytes to pull and what to name the file. Keep in mind you'll need to write one of the above code (depending on your workbench version) to transfer the sr executable from pc to amiga.
Now, sr (still work in progress) comes with another program on the pc side (linux) sendami. The idea is that sendami sends a special header before the actual file that define both the filename and the filesize.
So, on amiga side you type
sr
and on the linux side you type
sendami file >/dev/ttyUSB0
You may need to tune the baud number in sr.c for your amiga. (I'll make it an argument soon)
Should be as easy as
make
You may need to edit Makefile to alter a path or two.
The sendami will probably open the serial device at some point (code-wise) so the redirection would be unnecessary. Until then I am not sure if
stty 9600 -parenb cs8 crtscts -ixon -ixoff raw iutf8 -F /dev/ttyWhatever
is needed.
