[time-nuts] Prologix, 1 more quick ?

Prologix support at prologix.biz

Patrick,

There is no semi-colon after Prologix adapter commands (those that start
with ++). 
Try:

ser.write("++ver\r\n")

Regards,
Abdul

So sorry guys. I have been pulling my hair out for the last hour. One 
more question please.

Abdul sent me over a PySerial script just before I bought this item.

In the script there was line line like this:
ser.write("plot;\r\n")

I have tried ser.write("++ver;\r\n') and many other commands and 
carriage returns.

With ser.read(100) I get
'Unrecognized command\r\n'

So at least I have some communication. Could someone help me with the 
syntax?

Thanks in advance-Patrick
