failed to receive header signature

Hi i have a PC-104 chase with ZFx86 processor with IDE to CF adapter. I need to use the SBOOT.bin BIOS loader for my boot loader. It has two com ports built into it with LPT port and floppy drive on Board (SBC). SBOOT.BIN works till and error accurse in serial communications (Shock). Then the loader Halts in down load mode. The OEMPreDownload function works good single packet exchange (Shock). The OEMReadData stops when serial error accurse in the header download. Note the actual error can accrue in the data download as well, but by that time because of code structure it waits "bWaitInfinite = TRUE" in the RecvHeader function. So we now this is do to and serial error, no question. I now the hardware in both systems are working because in DOS I can send data all day long without them locking up. So this leaves us with the un-inescapable conclusion that the SBOOT.bin code is broke or the code in the platform builder is broke or the protocol do's not handle any errors. At all and is just poorly designed. So question, if I set the "bWaitInfinite = FALSE" in the RecvPacket call in the BOOT.BIN code, how do I handle the ERROR, or is there a rewrite for the RecvHeader function?
