[Elecraft] P3 Command set question

[Joe K2UF]

Not sure if this the correct address for this question.  I am trying to send
cammands to the P3 and K3 from a VB,NET program.  I tried several different
attempts to send commands to the P3 and K3.  I need the exact systax for the
code to send these commands.  If this is not the correct place for this
question please let me know where I would ask this question.
 
Any help would be appreciated.
 
Thanks
