ABAP/4:

CMCNVO ( output, &send_length, &rc );

If an EBCDIC host system is attempting to communicate with an R/3 ASCII machine, the data must be
converted, but it is not important whether the sending program or the receiving program performs the
conversion.
You can use include programs (RSEBCASC in ABAP/4, cpic.h in C) to convert data. It is even possible
to convert between code pages. You must maintain the relevant code page in the SAP system. In R/3,
you do this with the Transaction SPAD.
CMCNVO() converts from ASCII to EBCDIC.
CMCNVI() converts from EBCDIC to ASCII.
For the C functions SAP_CMLOADCONVTAB() and SAP_CMMODCONVTAB(), you use a special
conversion table in the file convert.txt (for the precise syntax, see the online manual BC
Communication: Programming).
