  Operating Modes

Driver mode

VScom Driver for Windows NT 4.0, 2000, XP and 2003
Driver Mode creates virtual Com port.

 

TCP Raw Server

Raw data transfer over TCP/IP. Accepts multiple incoming connections.

TCP Raw Client

Raw data transfer over TCP/IP. Connects to multiple hosts or devices waiting for incoming connections.

 

TCP Advanced Settings

Special settings for user-defined modes

UDP Mode

Raw data transfer by UDP. The NetCom is client and server at the same time. Timeout functionality, maximum packet size and a configurable trigger string define the packets of incoming data to send over UDP

 

Null Modem Tunnel

Connecting two NetCom used as virtual null modem cable.

IP Modem

The serial port emulates a standard modem. Operates by AT-commands, and dials to IP-Addresses instead of phone numbers.
Windows "INF"-Driver provided for installation.

 

Print Server

The NetCom accepts print jobs, and spools them to the attached serial printer. Operates as of RFC1197, similar to the line printer daemon in Unix-systems
