[time-nuts] HP5370B and GPIB

[Prologix]

Yes; ESC itself may be escaped by ESC. In other words, three characters --
CR, LF and ESC -- need to be escaped, by preceding them with ESC (27), if
they appear in the input data stream.

Cool! -- I assume that ESC also works that way, right (ESC ESC sends a
single ESC character)?  Is ESC just ASCII 27 as usual?  I can support that
in the GPIBLIB.DLL layer without much trouble.

I was called out of town on family business before I had the chance to
tinker with adding firmware-uploading support to prologix.exe, but it's
still on my agenda...
