communicating with an external device

[Tracy Lynn Mitzner]

Hello,
This question is related to sending information to an external device.  In the 
past, using Windows ME, I have been sending stimulus onset information to an 
external device using inline writeport commands such as "writeport &Hecd4, 
c.getattrib("Session") and writeport &Hecd4, c.getattrib("TrialList.Sample").  
I recently upgraded my operating system to XP and I am now getting an error 
message when i try to run those eprime programs, indicating that eprime cannot 
find the device driver.  I have updated the device driver and I still get the 
same error.  Since XP has such tight control over port access, it appears that 
I will need to send a command through eprime to access the 
I/O port.  Have any of you had similar problems?  And, if so, can you offer me 
any suggestions to remedy this problem?

Thank you in advance for any information you can provide.
