Ideally, I would like something The preferred way is to use the Xbtimer() Xbios call, using timer A, which is explicitly reserved for user applications. If you just want to measure the time interval, the easier way is to read the value of the 200Hz system timer by reading the LONG at location 0x000004BA. Remember to do it in supervisor mode, or else you'll get bombs. If you need examples of the use of either of the two techniques just send mail. -- usenet: {decvax|cbatt|cbosgd}!cwruecmp!bammi jwahar r. bammi csnet: bammi@case arpa: bammi%case@csnet-relay compuServe: 71515,155
