src/sexpots/sexpots.c
Log Message:
If configured COM port byte size is less than 8, strip high 8-n bits on RX

Some USB modems (reportedly, USRobotics USB modem) don't strip the parity bit of data received from modem connections operating in < 8 bit modes
(e.g. 7-E-1), as is normally don't with a modem connected to a UART, so we'll do that stripping (forcing to 0) here, as recommended by Deuce.

Nelgin, if you're doing some manually stripping of the 7th bit bytes received from 7-E-1 connected modems and then sent to your server/BBS over TCP, you shouldn't need to do that now.

Modified Files:
src/sexpots/sexpots.c
Log Message:
Increase buffer size from 4096 to 10000 in handle_call()

Log errors if/when comWriteBuf() fails.

This is to hopefully help to root-cause or even possibly resolve the issue reported in #synchronet by PyRoDrAkE:
"It all works well until the Dialup connection runs slower than 4800 baud
using SexPots. I connect from my XT at either 1200 baud or 2400 baud and it would just stop drawing midway."

There shouldn't be any write timeout in comWriteBuf(), so I don't know why
this would help, but it's worth a try. Logging any comWriteBuf() errors is
also a good idea in general.
