Tests ... [ write-to: -> ] [ read-from: <- ]
------------------------------------------------------
HP75C -> HP-9114B = ~2 sec.
HP75C <- HP-9114B = ~2 sec.

HP71B -> HP-9114B = ~2 sec.
HP71B <- HP-9114B = ~2 sec.

Emu71 Win -> ILPer = ~2 sec.
Emu71 Win <- ILPer = ~2 sec.

Emu71 DOS -> HDRIVE1 = ~1 sec.
Emu71 DOS <- HDRIVE1 = ~1 sec.
------------------------------------------------------
HP75C -> PIL-Box (115Kbps) -> ILPer = ~33 sec.
HP75C <- PIL-Box (115Kbps) <- ILPer = ~29 sec.
------------------------------------------------------
HP71B -> PIL-Box (115Kbps) -> ILPer = ~30 sec.
HP71B <- PIL-Box (115Kbps) <- ILPer = ~27 sec.
------------------------------------------------------
Emu71 Win -> PIL-Box (115Kbps) -> HP-9114B = ~30 sec.
Emu71 Win <- PIL-Box (115Kbps) <- HP-9114B = ~27 sec.
------------------------------------------------------
Emu71 DOS -> PIL-Box (9.6Kbps) -> HP-9114B = ~90 sec.
Emu71 DOS <- PIL-Box (9.6Kbps) <- HP-9114B = ~110 sec.
------------------------------------------------------

The above tests tend to demonstrate that the delay is induced by the PIL-Box.
