I have tried to set up a 2k network for dial up access but I can't get the modem to answer. Is this a 2k issue or an issue on the modem? It is a Hayes 56k internal modem.  I know if it was an external modem I could flip dipswitches on it.

Thanks.

That is a known isssue with Hayes modem. You can try this workaround by modifying mdmhayes,inf file:

Before you modify the entries, you should copy and save the original .inf files
with another name or to a different folder. You may want to restore the original
files if this workaround does not work well.
 
In the [M1806Reg] section, make the following change:
 
Change: HKR, Init, 2,, "AT&FE0V0W1&C1&D2S95=47<cr>"
 
To: HKR, Init, 2,, "AT&FE0V0W1&C1&D2S95=47S40=6<cr>"

After these changes are made, remove the modem from the Modems tool in Control
Panel and then re-add the modem. This will write the new .inf settings to the
registry.
