1197	! The TRANFER statement is a background process that allows the
1198	! computer BUFFER to be filled while the other commands are executed.
1199	! Therefore, other code (i.e. drawing data to the display data can go
1200	! here without hindering the measurement process.
1201	!
1202	! The ENTER statement can also be used to read part or all of the trace
1203	! instead of using the TRANFER statement.
1204	!
1205	! Remember that in FORM 1 data, which the HP 8530A uses in the FAST DATA
1206	! modes each data point is 6 bytes. The 6 bytes must be converted to
1207	! a real and imaginary pair.
