I do not have source code to the device driver. I would like to switch to DJGPP because I need TCP/IP support, which I plan to get with the Wsock library. Having read the FAQ's and documentation, I see that I can access memory below 1 MB, but am not clear if there is an explict Expanded Memory interface. I need the TopSpeed equivalent of ALLOWLOWSEG and FREESEG, which return and take selector. I am not an expert on the different DOS memory managers, and the intricacies of DPMI and EMS and XMS, and would greatly appreciate and advice. I have downloaded DJGPP and Wsock and was very impressed with the ease of installation and lack of problems in building the sample programs. thank you, Tom Friedel Ready Ink Incorporated Custom Internet Software and Web Sites 2500 E.
