Re: [CAD_CAM_EDM_DRO] ASAP: RS232C serial null modem

Hi John,

Null modem cables ARE only serial.
Your experiences with PC World mirror those of a friend on mine who rang to
ask them if they stocked PC power supplies as his had let the smoke out.
They told him that he would have to contact the original manufacturer of his
computer as these were probably 'specialist items' and anyway, their
computers didn't use them!!

Best wishes,
Ian

Subject: [CAD_CAM_EDM_DRO] ASAP: RS232C serial null modem


Hello fellow minions of the CNC under world,

Today I took it upon myself to call PC World (Don't ask me why), the
conversation is as follows: -
"Hi, do you have a null modems?"
"Sorry?"
"NULL modems?"
"We don't sell normal modems I don't think sorry."
"Okay, bye bye."
So, I visit PC world and find my null modems on the shelf approximately two
minutes after entering. I quickly find one labelled DB 25 to DB 9 serial
null, my lathe's RS232C is a DB25 and I want it to go into the DB 9 serial
on my laptop. Great! Now I notice this same cable is also stocked elsewhere
in the shop for these prices: -
Free (No label)
£19.99
£9.99
£8.99
So now I have my £8.99, I must ask you, I do want a SERIAL null modem and
not a parallel for this job don't I? I'm not very up to the scene on all the
ports and standards associated with them. Why the ASAP? Work it out man!
I've got a CNC lathe, a PC and a cable who's box I can't open until you
reply.

Thanks!
John Heritage
