HPBasic code for RS-232 on a 9826 with a 98626A card?

[Martin Hepperle]

You should not have to preset the variable E$.
Just use it and it should be dimensioned to the correct length by the ENTER command.
As already mentioned above, ENTER reads up to the defined end of line character (see registers of the I/O card).

Instead of a string you can also use a numeric variable, e.g. for reading voltage from a DMM
(It's all described in the BASIC and card manuals, the IEM card behaved like a HP RS232C card only with 3 select codes).
