#PRT: Redirection
Here's a good question for the Gurus. We're working on network software, and
we're considering ways to implement printer sharing. What is the best and
safest system method for intercepting calls to PRT:? Is it true some programs
access PRT:, while others access "printer.device" directly? How can we get
around this? Some programs let you change the PRT: to something else, some
don't. Also, there is no system method for selecting which printer should be
considered the PRT: printer. In other words, we need a mechanism for
supporting multiple printers, too, each with their own printer driver
selection. Is it true that third-party serial boards can't be used for the
PRT: printer, because it only selects between SER: and PAR:?
