dial()

We are programming an automatic credit card validation sceme for
our transactions. Currently our sales people have to dial the
bank by hand and retrieve credit card validation with painstaking
care. We hope to program a dialer, validator.

The problem we have is in using the Interactive sub-routine dial().
This routine is located in the programmer's reference manual, section
3C. The documentation even lists the alarm call usage as a potential
bug. However we have been unsuccessful at mastering its usage.

One problem is using the debugger after having made a call to dial().
Apparently dial() makes use of the Unix SIGALRM signal even after
the process has returned from the dial() sub-routine. This makes
debugging quite difficult with signals constantly being set to the
process.

Does anyone have experience using this sub-routine??? Or perhaps there
is another method of parsing the uucp files to accomplish the same
feat??
