- The problem is not with the modem, it is with the comm program.
- Using a debug filter in the comm program, which shows incomming
- bytes with all control codes represented in ascii rather than
- by the results of their intended action, I was able to actually
- see the character sequence that was causing the problem.
-
- The problem arose in an article in a usenet group. Replies to
- the article which included the escape sequence also caused my
- comm program to screw up. Presumably the people that replied to
- the article did not have the same problem. This seems to imply
- that their comm program is handling this better than mine.
-
- Anyone using xtalk communicator (came standard with my USR 14.4
- modem) been able to get around this problem?
