For the control characters for the data transmission protocols ( , , ,
, ), any other ASCII characters can be chosen using the following machine
parameters (for table of ASCII characters, see Appendix). If these machine parameters are loaded
with a nought, the standard settings given in brackets are active (as for FE1 and FE2 operation).

When selecting ASCII characters, it must be ensured that the control characters are not arbitrarily
mixed and that no figures or letters which occur in the transferred text are used.
Example: The control character for Start of Text (MP5200.x) must not be assigned to ,
otherwise transmission will stop when software handshaking is set on the peripheral.
