I'm hoping somebody may know a command I can type to check the serial on my
osborne is working
Lately I'v been online with a c64 serial cable and server software accessing
the internet with a term program is ok would post with it but for it not
working with https pages
for some reason the o! isnt sending signals through the port as i am able to
monitor the connection with the pc
Is it possible i have to change the port with a command line as its able to
be serial or parallel according to the help files within cpm
For some reason its not sending cts or dsr signals unless the serial port
isnt true 232 compatible where could i get a pinou for this port and clues
on switching the acia chip which i believe is the serial controller
now i have a shell account I'd like to go online with an osborne
Thanks
Garth

Long story short: Once (many years ago) I ran into a bad serial
cable. It was a 'factory supplied' cable so I didn't think it could be bad,
but it was. I've been out of this game for long enough to've forgotten the
intricacies of command line IOBYTE setting, but you might want to confirm
that your problem is not poor connectors/cable by temporarily using a
known-good cable in its place.

Garth, here is an old serial terminal/modem program I wrote 20 years ago.
Looking at it, I was changing the iobyte between 148 and 149. Hope it
helps.

-J

program modembb;
{ Bare Bones Modem Program - modify to your heart's content }
{ Originally written for Osborne 1 with Hayes 1200. But, as }
{ it uses standard cpm bios calls through Turbo, source code}
{ should be transportable (CRT: on Osborne is serial port). }
{ John Garza Nov 23, 1985 }
{---------------------------------------------------------}
var
iobyte : byte absolute $0003;
echo : boolean;
autolf : boolean;
quitflag : boolean;
t : byte;
r : byte;
{---------------------------------------------------------}
begin {main}

echo:=false;
autolf:=false;
quitflag:=false;
iobyte:= 148; { 10 01 01 00 }

while quitflag=false do
begin
t:=0;
while t <> 27 do {while t <> escape}
begin
if bios(1) <> 0 then {console status}
begin
t:=bios(2); {console input}
bios(5,t); {punch output}
if echo then bios(3,t);
if t = 13 then {make cr --> cr lf}
begin
bios(5,10);
if echo then bios(3,10);
end;
end;

iobyte:= 149; { 10 01 01 01 }
r:=bios(1); {console status with con:=crt:}
iobyte:= 148;

if r <> 0 then
begin
r:=bios(6); {reader input}
if r > 127 then r:=r-128;
bios(3,r); {console output}
if echo then bios(5,r);
if autolf then if r=13 then bios(3,10) {show crlf if autolf}
end;
end;
quitflag:=true; {Quit if ESC character keyed}
end; {stop program if quitflag true}
end.

The Osborne does not have standard RS232. It goes from 0 to +5V
Years ago I used an external negative supply with a PNP transistor
to furnish the negative voltage.
