Paper Tape Emulator in Basic

[Jim Beacon]

Hi,

has anyone tried to write a paper tape emulator in BASIC? I've had a go in
GW-BASIC, but I suspect that the implementation of the language is too slow
to reliable drive the serial port - it doesn't always pick up the paper
advance signal (I've tried using both CTS and DCD as inputs).

Will I have to go to a machine code routine to get the fast port access?

I look forward to replies.

Jim.
