Re: ASYN Addition

[Andrew Wagner <apwagner@u.washington.edu>]

I'm using ASYN 4-13-1. Only the sleep after asynOctetConnect is really needed. Let me know if there is problem with this version of ASYN or if I should set the timeout to something other than the default. 

Cheers, 

Andrew

I've compiled EPICS and ASYN on 64 bit darwin (OSX 10.6.4) with 2.5 GHz Intel Core 2 Duo so perhaps without sleep statements ASYN is writing things before the socket is really established. I have had no trouble with the device support and can issue read/write commands without error with dbtr record_name.

The function connects to a socket exactly as in TDS3000Reboot but here the user can input both a port number and custom boot/init string. For example when I want to boot my PROLOGIX-Ethernet GPIB controller I issue

Here the IP address is 172....., the port is 1234 and the last string is the message. The command is registered in drvAsynIPPort . So far this is just my private code and I was wondering if I could commit it somewhere or submit it to an expert for approval. If anyone is interested let me know and I'll send it to you.
