Hi, I am hoping someone may have done the following or
could point me in the right direction.
I am trying to connect an HP logic analyzer to my AT&T PC
to get analyzer printouts of the screen. Now the analyzer
has an RS232C port and can be configured to use several
handshaking protocols (e.g., Xon/Xoff). My major concern
is the difficultly(ies) in accessing the serial port and
writing the 'data-collecting driver routine'.
The ideal operation(?) is,
1. HP analyzer sends data (already suited for Epson prints)
2. the AT&T collects ALL the data (in the background,
interrupt driven)
3. then, the AT&T sends the (raw) data to the printer

My documentation is scarse and not at a 'low enough' level
to accomplish this 'data-collection driver'. I am hoping
someone may have done something similar (maybe some code??)
and can provide useful hints on doing the above.
Thanks In Advance
