Though I'm pretty sure there isn't much demand for dial-up BBSes today (30Kbps!), there has been enough interest from sysops to at least justify some effort (in my mind) to attempt to relive the BBS days of old, using actual *gasp* modems!

 +Note: SEXPOTS v1.25 and earlier did not supports comments on ''.ini'' string value lines as shown above. As of v1.26 (and later), string values (e.g. com device name, modem strings, hostname, etc.) are terminated at the first white-space character so white-space characters are **not permitted** in the string values of the SEXPOTS ''.ini'' file.
 +
 +Note: Support for the ''[modem] ReInit'' key was added in SEXPOTS v1.27.
 +
 +==== Modem Settings ====
 +
 +Modem settings that SEXPOTS will work best with:
 +
 +^ AT Command ^ Description ^
 +| ''C1''     | Modem asserts the DCD signal when it makes connection with another modem and de-asserts the signal upon disconnect. |
 +| ''E0''     | Command echo from the modem is disabled. |
 +| ''Q0''     | Result codes are sent by the modem. |
 +| ''V1''     | Verbal result codes are sent by the modem (instead of numeric result codes). |
 +| ''W2''     | When connecting, the modem reports the line speed (just once) in the CONNECT message. |
 +| ''&C1''    | Modem asserts the DCD signal only when carrier is present. You will need to set ''IgnoreDCD = TRUE'' if your modem does not support this. |
 +| ''&D2''    | When the the DTR signal is de-asserted (on->off transition), the modem hangs up. |
 +| ''S2=43''  | Escape sequence character: ''+'' |
 +| ''S3=13''  | Carriage return character: ''^M'' |
 +| ''S3=10''  | Line feed character: ''^J'' |
 +| ''S95=3''  | CONNECT result code indicates DCE speed instead of DTE speed, append /ARQ in error-correction mode. ((for modems that support this S-Register)) |
 +
 +These are typically the default factory settings for modems manufactured in the last 30 years.
 +
 +If these settings are not your modem's factory defaults, then you may need to make adjustments to the modem initialization string or (if unsupported by your modem), make other adjustments to your configuration file or command-line options.
 +==== Prompting for a TCP Host ====
 +
 +By setting the ''Prompt'' key value (to a text string asking the remote user to press a key), you can have SexPOTS connect to one of a set of TCP hosts by creating additional ''[TCP:x]'' sections in your ''.ini'' file, where ''x'' is a single non-control character that the user may respond with to choose that host to connect with. If the user does not respond by the configured ''PromptTimeout'' duration (default: 60 seconds) or responds with an invalid key press, the default host is connected to.
 +
 +Example .ini file (with default values given):
 +<file sexpots.ini>
 +Prompt: "Hit 'P' for PBX or ENTER for BBS now"
 +
 +[TCP]
 +Host=mybbs
 +Port=23
 +Telnet=true
 +
 +[TCP:P]
 +Host=thepbx
 +Port=2600
 +Telnet=false
 </file> </file>
  
Line 187: Line 212:
   net stop sexpots   net stop sexpots
  
 +==== DebugView ====
 +
 +When running SEXPOTS as an NT Service, you may want to use a debugger viewer (e.g. [[https://docs.microsoft.com/en-us/sysinternals/downloads/debugview|DebugView]], run as Administrator) to see the detailed log messages:
