I have an application that needs to send a piece of equipment command lines in the following form:

SOH TYPE [##] STX [DATA_TEXT] ETX [BCC] CR

Bracketed items are optional data. TYPE, ##, and DATA_TEXT are all text. SOH, STX, ETX, and CR are all Hex values but I get an error when trying to send a hex value with MSComm. My question is...how would I send the following parameters using MSComm?

&H1 P AA &H2 Hello World &H3 &HD

Thanks In Advance,
Randy

Thanks for the response.

How would I send the hex value &h1EE? I get an error when I use the chr() function.

Thanks Again,
Randy
