Data is transmitted for SEND(90) and RECV(98) for all PCs when
SEND(90)/RECV(98) is executed. Final processing for transmissions/recep-
tions is performed when END(01) is executed in C2000H Duplex CPUs, and
during servicing of peripheral devices and Link Units for all other CPUs.
To ensure successful SEND(90)/RECV(98) operations, your program must
use the SEND(90)/RECV(98) Enable Flag and SEND(90)/RECV(98) Error
Flags to confirm that execution is possible. The following program shows one
example of how to do this for a SYSMAC NET Link System.
