I am thinking of buying a new lap-top (nothing fancy) but I note that none seem to have an RS232 port any more.
I MUST have RS232 because one use of the laptop would be in communicating with all sorts of strange devices that use RS232 (using all sorts of software).
I know that USB to RS232 converters exist BUT now to the question:
One piece of software I use is Hyperterminal and it "looks" for ports (eg RS232), but as far as I can tell, doesn't see USB (my son's laptop only has USB, and Hyperterminal only comes up with TCP, modem and COM4 (IIRC) which is the infra-red port).
And all the other software (i.e. other than Hyperterminal) just seems to find COM1 and then works.
Thus, does anyone know how all these RS232 bits of software could find the "port" via USB? Would the USB to RS232 converter cable have software that turns USB into COM1?
Thanks all. Some interesting ideas. However, have you seen the prices???!!! Knocking on the door of £100!! I only want a very basic laptop for my current purpose and have got my eye on a special offer low spec Dell for £350. Bearing in mind all laptops used to come with RS232 as standard, I'm now struggling with the idea of spending a quarter the overall cost on a very low-tech piece of add-on kit called RS232!!!
A fair price would be about £10!!
Oh dear...perhaps I'll make my own...
You've given me some pointers to try searching...thanks. I'd be interested in hearing from anyone who has actually tried to do what what I want.
