[comp.sys.mac.comm] WANTED sample code in think pascal for communications

jp10@GTE.COM (Jeffrey Perry) (12/19/90)

	The title says it all. Please send me any sample code you might have
    in think pascal! Of particular interest would be how to handle sending
    a single carriage return to a modem. I am currently having problems with
   this particular aspect of communications. For some reason the carriage return   is not echoed so my readline routine doesn't stop. Upon careful tracing 
    using think pascal 3.0 I have discovered something very strange; aa null
    character is being echoed (character 0) instead. Also I am using strings
    and concating characters onto them. I then try to clear them by doing
    someething like a:='' This seems to work ok, but eventually the length
    byte of the string gets messed up. Help! Any ideas? Any suggestions on better  ways to handle the strings??


Thanks in advance! Please respond directly and i will summarize!
