RS232 - Freeze

[Fabio]

Congratulations, your drive is very good. But I have a problem in the following code:

(SERIAL.BAS)
while (1)
gosub do_in // freeze if no char ????
if urb.actual_length>0 then
color 7,0
print mid$(buffer,1,urb.actual_length);
end if

How to make the system do not wait ? Is it possible?

SERDRV.SYS works, but is not compatible with my hardware.

Thank you.

SERIAL.BAS and SERDRV.SYS are written to work with Georg Potthast's USB drivers, not mine. His API is completely different than mine, and you'll need to contact him.

Sorry, I put the 2 links in favorites and selected the wrong.

It looks like SERIAL.BAS could be converted to work with my API without too much difficulty, if you wanted to experiment with that. I wouldn't be willing to do it, however, because I don't have the time nor do I have a device to test with.

[Fabio]

I'll try. USBDEVC>CPP is very similar, I think it will work. When I have the code, running or not, I put it here.

Good Luck!
