FTP Programming
Practical
Programming for AS/400 FTP Automated Interfaces
FTP is one of the most widely used modes of transferring data between systems, regardless of their operating systems. The link above features an article that I have written on AS/400 Automation.
Socket Programming
At the heart of the "Client-Server" expression, Sockets are a standard as well as a method of communicating. This is one of the most versatile and well-known methods of communicating over an IP network.
Most socket code is done in C, but IBM has recently come up with RPG implementations also. Both C and RPG implementations are supported on the AS/400
APPC Programming

IBM On-Line library also contains:
* OS/400 APPC Programming V4R1
While APPC and APPN are deemed to be eating TCP/IP's dust, this is still a widely used protocol, as there still are many IBM machines using this method of communication.
On the AS/400, an APPC connection is a matter of creating an ICF file linked to a controller, which itself is linked to a device. Any RPG or C program can access these files with relative ease.
Information on APPC Programming can also be found in the IBM on-line library.

Integration Solutions with MQSeries Integrator (Red Book)
MQ Series is an IBM product for secure, guaranteed communications. Think of it as the "FedEx" of interface deliveries. If you are sending data and somebody cut the wire in the middle of the transmission, MQ can be configured to remember where the transmission was interrupted and resume from there. This product may look heavy but it is a good choice for mission-critical transmissions.
