Windows serial port

ruby-talk
1

I'm trying to talk to a Windows serial port. COM1: in fact.

Question 1. What is the best way to do this?

Question 2:
   Currently I'm trying to use
     http://ruby-serialport.rubyforge.org/
   and getting bizarre error message whenever I try to open a port for all
   values of port I can think of...

(eval):13: in `create': No such file or directory - (Errno::ENOENT)
   from (eval):13: in 'open'

I presume this must be in SerialPort::open

Any suggestions what to do? This is using ruby-1.8.1 on win2k

Question 3:
Anybody have a compiled version of http://grub.ath.cx/win32serial/?

Thanks,

You might like to read what I worte over there:

Hmm, be sure that no other programm is reading/writing to/from that port. IIRC there may only be one program ocnnected to a certain port at a given time.

I can remember I compiled it using MinGW. The resulting binary worked fine with the one-click-intaller.

As far as I remember, I ended up using Win32serial in the end, although I would have stongly referred ruby-serialport (because it's available for both unixoide OSes and Windows).
Unfortunately ruby-serialport dropped some bytes every now and then on the system I had to use at that time. (which was an old Win98 box, so you might try ruby-serialport on your 2K machine).

Thanks,

Hope that helped.
