/*
 * sercfg.c - the serial-port specific parts of the PuTTY
 * configuration box. Centralised as cross-platform code because
 * more than one platform will want to use it, but not part of the
 * main configuration. The expectation is that each platform's
 * local config function will call out to ser_setup_config_box() if
 * it needs to set up the standard serial stuff. (Of course, it can
 * then apply local tweaks after ser_setup_config_box() returns, if
 * it needs to.)
