Appendix C.1. 

Driver Limitations and Exclusions 

The  Carrier  DataPort  driver  does  not  support  the  following  functions.  Send  Data  Periodically,  Stop 
Sending,  Xoff,  Xon,  Omit  24  Character  description,  Include  24  Character  description,  Read 
Configuration.

 

 

The Carrier DataPort driver is not capable of configuring the DataPort device.  Software provided by 
the  Carrier  Corporation  is  required  to  do  this.  The  DataPort  device  requires  configuration,  so  that  it 
connects to the appropriate CCN devices on the CCN communications network. 
 
If the total length of the response from a read table query is more than 3000 bytes long, the driver will 
produce an error.
