The 10 means use 1200 baud (determined by experiment). 300 baud is the default, and can be forced by using either a 0 or an 8 in place of the 10. On to my next question: is there a standard Action! routine that I can use to determine if there are any characters to read from the R: device? If not, has anybody written one? Thanks again. :: Jeff Makey Makey@LOGICON.ARPA
