# Dialer and Modem Troubleshooting

POSSIBLE PROBLEMS
You have one or more of the following serial connectivity problems.

- Your modem is not directly supported by the LAN WorkPlace Dialer.
  - If your modem is Hayes compatible, select the Hayes compatible modem type. This will limit you to a 2400 baud connection.
  - Connect to your Internet Service Provider.
  - Once you are connected to your Internet Service Provider, click here to obtain the latest update to the Dialer's modem list.
  - After extracting, move AIOMDMS.MDC to \NET\HSTACC.
  - If your modem is still not supported, click here to obtain the tools to create a modem entry for your specific modem.
  - Use the NWCWRT.EXE patch to edit AIOMDMS.MDC and add support for your modem.
  - Retry your dialer operation again.

- The Dialer does not connect when calling.
  1. Check your serial hardware.
  2. Watch the dialer connect, using SLPMON.

- Your modem does not answer (a call-back call).
  - Make sure that the TCP/IP serial support is loaded.
  - Use SLPMON to identify problems in the serial driver configuration.
