    I have a strange illusive problem, help me because i’m finished, no problem anyway. I’m working at a ms-dos script, batch file and:
    I cannot send commands to the com1 external modem anymore, after i reset computer or after i open Modem options/Diagnostics and Querry modem. I might think the com1 port becomes blocked or the system doesn’t recognize COM1 anymore, because when i COPY COM1 CON, ms-dos gives the message ” 1 file(s) copied.” that is not correct. I’m using w2k pro.
    The thing that solves this is to enter Hyperterminal and set it to autoanswer then exit, or to launch/exit another program “Modem Spy” that also sets the modem on auto answer.
    I need to find what’s happening so i could avoid this, or a way to unblock the port or the modem, or to replace COM1 with another variable known as COM1 by the system.
    …Thanks for reading
