10BaseT and I-Net 5.01 Problem

Hi there, Does anyone have any problem with I-Net 5.01 on a client machine that uses an ethernet card with 10BaseT connection? I'm currently configuring a Compaq PC client with a 3com 3c509 card having 10BaseT connection to talk with my server. My server is running Online 6.0; my PC is using FTP PCTCP 2.3.1 and I- Net 5.01 WD1. I tested with the ILOGIN.exe that came with I-Net 5.01 and stores database. The customer table did come up but we received a WINDOWS SYSTEM ERROR Cannot write to device AUX. When I use I-Net 4.10, the were no such SYSTEM ERROR. Can any help? - Ken Chow kcchow@solomon.technet.sg
