For instance, I use a Hayes Smartmodem-1200 with my Compaq portable P.C. under PCDOS 2.1; the comm s/w is YAM (Yet Another Modem) by Chuck Forsberg at Omen Technology, and I like it very much, partially because it permits me to define the amount of time that passes before a loss of carrier is interpreted as a loss of connection, in the range of about 0.05 seconds to about 15 seconds. (BTW, if anyone would like further info about YAM, let me know via mail.) -- --Dwight Ernest KA2CNN \ Usenet:...vax135!timeinc!dwight Time Inc.
