I am looking for some C routine that allow you to access the COM port on PC's My Compiler's (Microsoft C) library functions do not suport high speed transfer (nothin over 300 baud), also how would you go about accessing the other 6 COM ports. All the functions I have seen only support COM1 and COM2. Any help would be appreciated. Thanks in advance. Dave. opr_deforest@nradm.enet.dec.com or on Easynet nradm::opr_deforest

It will set up your ports for interrupt driven communication up to 19.2Kbaud (although they don't recomment running to many that high) plus lots of control (Xon/Xoff, CTS/RTS, Kermit ). It all comes as libraries for MSC5.1 (maybe 6.0 now?) or other popular DOS compilers. If you have 6 other COM ports, you must have a special board in your PC. Greenleaf support many of the popular ones but you may want to check before you buy.
