Use ODBC que vem com o cd de instalação, ou baixe em picksys.com ou ftp://ftp.picksys.com/ . também. pode tentar Sockets.

Tem muito tem que você. postou essa dúvida, caso ainda queira usar Delphi com D3 eu posso procurar p/ você. um manual do ODBC e Sockets/D3.

Um exemplo 

necessita do odbc pick instalado e configurado na maquina.
necessita da importacao do d3clodbc.dll, e no path
necessita de odbcsrv -d no servidor, se for usar o odbc

antes de rodar o programa em delphi, rode o programa listener no pick.

este e apenas um exemplo simples

peguei algumas rotinas na internet e as juntei, corrigi e melhorei.

Se fizerem alguma alteracao, ou implementacao com sockets, podem me enviar.
A principio, estava pensando em implementar um socket que executase um sql ou programa, e  retornasse o resultado, ou 
gerasse um arquivo e gravasse no  /tmp para o delphi ler e processar.

O programa sender, serve para comunicacao pick a pick. surgiro pegar os originais se for o caso, no link acima.


Parece bem complicado, mas depois se entende o porque, do programa ser assim.
