Tim,

Developing on Win95, SAS 6.12 TS050, to run under Win NT Server 4.0 SP4 with SAS 6.12 TS050. I tried both the WAIT and the ZERO options with COMTIMEOUT but got the same results - yes, it seems like it is not working as documented. The modem connects fine with a dumb terminal, which I am using to see what responses SAS should be looking for.

Cheers,

Tim
