I am trying to get the Garmin Mapsource program to communicate with my GPS over a serial port. Mapsource autodetects the GPS but will not transfer data to or from it. For debugging purposes, I have connected a null modem cable from my Motherboard serial port (Intel 865G chipset) to a USB/serial adapter. I can communicate perfectly between two minicom terminal programs, but when trying to communicate between minicom and teraterm under wine I have trouble. Characters typed in the teraterm window appear in the minicom window immediately, but characters typed in the minicom either take 10 seconds or so to appear in the teraterm window, or do not appear at all. The symptoms are identical regardless of hardware handshaking settings or whether the teraterm/wine program uses the MB or USB serial port. Starting teraterm, typing some characters into minicom, and quitting teraterm produces the following trace: Code: fixme:font:WineEngCreateFontInstance Untranslated charset 255
