Concerning ProComm V2.3 (a few years old now) In the manual (p.14), I find the following paragraph: > Modem CD Mask > > The modem Carrier Detect mask is used by ProComm to determine whether or > not a hang-up has been successful. The default value is 32. It may be > necessary for you to experiment with this parameter in order to determine > the correct value. Values tried should be powers of 2, i.e. 12, 32, 64 > and 128. In general, if the hang-up command (ALT-H) correctly reports > the results of the hang-up attempt, then the CD mask is correct. > ... > The following values may be used as guidelines, although cabling and other > considerations may make them inaccurate: > 16 Hayes external, Prentice POPCOM > 32 USR Courier, Cermetek Security Modem > 128 Hayes internal, ... I just changed modems, the ALT-H command still works (drops the DTR and you can hear the relay click onhook), but ProComm now reports "Hang-up failed". I then experimented and found that 128 now worked (was 32). But... QUESTION: what do these numbers refer to? I've read a few modem manuals and never found anything I could link with this. Anyone have a clue what is going on here?? I fear it must be very simple (I might be quite embarassed) but I can't figure it out! Hope it's not an FAQ (otherwise might be double embarassed!) -- Pierre LEWIS ESN 852-8207 Corwan: lewis@bmtls30 (aka bnrmtl, 47.64.3.30)
