[Gmecm] '165 expertise???

[Don Brown]

I can't be a lot of help here because I use diacom with our 7165, and it's 
flawless with the parallel port.  At work though our equipment uses rs-232 
ports for communication. So for the new laptops without the serial ports we 
need to use the usb/serial adapters.  Our timing is critical and as long as 
the serial port communication is set up we don't have problems.  All 
adapters that we've seen are packaged with their own set of drivers and we 
install them rather than trusting the drivers supplied with windows.  I'll 
try some software and hardware to talk to the 7165 through a serial port 
with a usb/serial adapter to see if I have the same issues and report back.

Serial to USB  adapters are a study onto themselves as is getting serial
ports to recognize that they have a hook-up trying to work.  Most everyone
that sells the equipment (Moates as an example) have their own adapter they
want you to use.  I bought it and it worked for me on an IBM Thinkpad.  A
RadioShack adapter did not.  I'm certainly not a computer expert but I
believe it has something to do with the particular BIOS of the computer that
you are using.
