A job advertised today in New Zealand requires someone who has knowledge of Borland C for DOS, (why oh why did use Microsoft C and I still have the manual, demo programs on DOS palette management). This isn't that surprising as I've noticed that some petrol stations (and from working on them) race track terminals still uses either DOS based programs or OS2. Just in case anyone here is into RS232 via DOS here is part of the job ad. " Software Engineer An immediate start for a Software Engineer with an intermediate level of commercial experience and in depth knowledge of Borland C for DOS to design and implement software solutions for new and existing products. It would also be valuable to have experience with ISO communications protocols as, working in a small team; the immediate work is to implement a new communications suite for a set of DOS based platforms over an asynch RS232 pipe running over radios. The suite will cover everything from high level user interface, including message logs and setup areas, down through addressing and retries and finally at the base layers of forward error correction methodology and port access.
