Subject: StreamDevice/ASYN connection to a Telnet port

Dear All,

I am connecting to a Gamma Vacuum SPCe ion pump power supply. This device has an ethernet port which accepts telnet connections.

I set up StremDevice to communicate with it on port 23,

I have  asyn Trace Masks set as follows:

asynSetTraceMask("SPCe",-1,0x09)
asynSetTraceIOMask("SPCe",-1,0x2

I have a problem in that the response string , which I expect to look like  "OK 00 7.90E-13 TORR" 

appears like this:
