If you manually dial using cu or tip, what connection speed does the modem report? > Here are my modem hardware setting (with explanations in square > brackets): > > BAUD=9600 PARITY=N WORDLEN=8 > DIAL=TONE ON HOOK CID=0 > > &A3 &B1 &C1 &D2 &G0 &H1 &I0 &K1 > [&An n=0 Disable /ARQ Result Codes > n=1 Enable /ARQ Result Codes > n=2 Enable /Modulation Codes > *n=3 Enable /Extra Result Codes > &Bn n=0 Floating DTE Speed > *n=1 Fixed DTE Speed > n=2 DTE Speed Fixed When ARQ It is somewhat worrysome that your modem is reporting 9600 BAUD in the fixed DTE speed setting. I don't know about USR Internal modems, but at least some implementations will pace the data flow rate to the reported DTE speed to avoid overwhelming the host with quick bursts of interrupts. This might be the reason for your slow connection speeds. It's been a while since I've used the proper incantation to reset the speed on a USR modem, but I think with a serial modem, the procedure was to connect to the modem, repeatedly type AT to get its attention, put it in variable speed mode, reconnect at the desired speed, and set &B1 to get it back to fixed rate. Probably something similar will work with an internal modem. The modem will probably peek at the UART speed control register to pick up the desired DTE rate and save it to its non-volatile memory. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
