1163 * *
1164 * Sets the specified port's configuration settings. IMPORTANT: not all *
1165 * port drivers support this; the standard OS/2 serial and parallel port *
1166 * drivers do NOT. Depending on the port driver, there are two possible *
1167 * outcomes when this API is not supported: *
1168 * A. Port driver does not have an entrypoint for SplPdSet. This is the *
1169 * case for any port driver using pre-Warp conventions. RPUPortSet will *
1170 * return 0 and RPUERROR will be "1: DosQueryProcAddr". *
1171 * B. Port driver supports SplPdSet but does not (correctly) implement the *
1172 * BIDI_SET_PORTDRV command. This is the case for some third-party port *
1173 * drivers. In this case, whether or not RPUPortSet returns a success *
1174 * code entirely depends on how conscientiously the port driver itself *
1175 * is written, but the "INITIALIZATION" key (and possibly others) in *
1176 * the port's entry in OS2SYS.INI will not be updated. The application *
1177 * should always check for this after calling RPUPortSet! *
1178 * If the application determines that either of these failure conditions has *
1179 * occurred, it is advisable to call RPUPortDialog as a fallback measure. *

1188 * 3. Byte sequence representing the new port configuration. The format *
