application" error message (when run on XP) and reportedly will allow target
executables to run on non-SEE (pre-Pentium III) CPUs. Seriously, anyone really
running Windows XP on a Pentium II today? I guess it's possible <shrug> and we
really get little benefit from SSE in Synchronet.

I couldn't get Windows 2000 running in Hyper-V, so I guess Windows 2000 is
now officially unsupported by Synchronet (and long unsupported by Microsoft).

Thanks to Android8675 for the bug report and Rushfan for the solution tip.

loop immediately upon socket receive error (e.g. 54, ECONNRESET).

from everything that links with the sbbs library.

Also, use the absolute path to the 3rdp stuff to silence CMake warnings.

New sexpots.ini [modem] keys:
Answer (default: "ATA")
Ring (default: "RING")
ManualAnswer (default: false)

- configurable via [modem] CmdRetry, default value is 2 retries
- drops DTR, delays and the raises DTR before retrying modem commands
Improved log output:
- don't log COM Device value when passed live com handle/descriptor on cmdline
- log COM Device value in modem command/response errors
- more debug-related log output
Fix modem re-initialization time-out (off by one)
- ReInit value of 1 would result in reinit every 2 minutes of inactivity

many minutes of inactivity waiting for a caller (like sbbs2).
(defaullt: 60 minutes, 0 = disabled).

example sexpots.ini in docs/sexpots.txt) - now truncates string values (com dev
name, init strings, etc.) at first white-space char. Bug reported by Netsurge.

(over-riding the default log level of "info").

("^M" to send a carriage return, for example).

HangupAttempts is configurable in the [com] section of the sexpots.ini file.

I will add daemonizing when two conditions are met...
1) Someone confirms that it works.
2) Someone confirms that it works on Linux.

I'm particularily worried about the comWriteByte() and comWriteString()
error handling (or lack thereof)... Especially in modem_send()

Also, I think the timeout mechanism should be in comReadByte() itself
so we don't need to use while(1) { poll(); yield(); } loops.

I assume that Win32 supports read timeouts... if not, a single loop and
only for Win32 would be preferable to having it multiple places.

the key doesn't exist.

over-riding sexpots.ini key values with default values if a secondary .ini file
is specified on the command-line.

Converts 'P' and 'O' CID responses to "Private" and "Out-of-area".

No need to advertise Telnet term speed support after reporting term type.
Now ACKs Telnet term speed option when requested.
Now sends Caller-ID info when Telnet location requested.
New sexpots.ini [tcp] option TelnetAdvertiseLocation, set to true to send a
"WILL SEND_LOCATION" command during connection.

protocol.

* Raise DTR again after dropping to hangup or modem won't auto-answer
* Skip white-space prepended to modem messages (e.g. "\r\nRING")
* Configurable delay before dropping DTR (to allow TX buffer to empty)
* Cosmetic issue with banner

and .ini value ([COM] BaudRate) modification with a few minor changes. :-)
