ttg "Talk to gaw" is intended to let your application controls gaw with
|
||
|
|
command lines send over a socket. To enable this you need to run gaw with a
|
||
|
|
port number, and use the same port in your application :
|
||
|
|
gaw -p 1946.
|
||
|
|
|
||
|
|
For each line sent, gaw echo back a line feed or an error message and can be
|
||
|
|
used for synchronization, if needed.
|
||
|
|
|
||
|
|
In directory ttg, you can find an example C program and an example Perl program
|
||
|
|
talking to gaw.
|
||
|
|
|
||
|
|
Using this method, it is possible to add a column of data to a previosly
|
||
|
|
loaded array of data.
|
||
|
|
|
||
|
|
Here are the keywords used to send commands.
