I have a US Robotics 5610B modem (Internal 56k V.92 modem) running on WIN 2000. I have two applications for this modem. During the day I want to verify credit cards. My software requires to turn off error correction, data compression, match port speed, and set port speed to 1200. The AT command is "AT&F&H1&R2&M0&B0&K0&N2". This works fine for the credit cards, however, the when I use the dialup connection, the error correction seems to be disabled (even though it's checked in the configuration box. Is there anyway to force it to be on?
