dp_connect

Syntax

 

dp_connect channelType args

 

Comments

 

dp_connect establishes a Tcl-DP channel.  The channelType is based on the channel types that are installed; the base Tcl-DP package comes with TCP, UDP, IPM, serial and email channels.  The args are specific to each channel type since TCP has completely different options than serial ports do.  Please see the channel documentation for information on the available arguments for that channel type.  Once the channels are established, one can configure them using the normal fconfigure process.

 

All I/O on these channels is performed using the standard Tcl puts/gets or the Tcl-DP I/O commands: dp_copy, dp_send, and dp_recv.

 

dp_connect returns the ID of the new channel.
